| How to Write Fractions on a Calculator Posted: 13 Apr 2021 01:00 AM PDT Calculating numbers that contain fractions can be tricky, even when you're using a calculator. You may be able to write a fraction on a calculator using the fraction button. If your calculator doesn't have this feature, use an online calculator if you're allowed to do so. As another option, you might turn the fraction into a decimal or turn the fraction into a percent. [Edit]Using a Fraction Button on a Scientific Calculator - Switch your calculator to math mode, if necessary. Push the mode button to open a menu. Select "math" from the list to start math mode. Check that your screen says "math" to make sure you're in math mode.[1]
- Your calculator may not have a math mode.
- Some calculators will use a fraction button even if you don't have a math mode.
- Push the fraction button to enter your fraction. Look for a button that has a black box over a white box, x/y, or b/c. Push this button to open the fraction feature on your calculator.[2]
- When the fraction feature is on, you should see a fraction template on your calculator screen. This will look like 2 blank boxes, one on top of the other. There will be a horizontal line separating the boxes.
- On some calculators, the boxes are separated by an "L" that acts as the horizontal line.
- Enter the numerator in the top box. Your cursor will start out in the top box on the fraction. Use the keypad on the calculator to type in the numerator, which is the top number in the fraction.[3]
- For instance, let's say your fraction is 4/5. You'd type "4" into the top box.
- Push the down arrow to move your cursor to the lower box. Find the arrow buttons on your calculator's keypad. Then, type the arrow that points down to move your cursor to the lower box in the template.[4]
- If your template uses the "L" to separate the boxes, you may need to hit the arrow that points to the right to move the cursor. Try that arrow if the down arrow doesn't work.
- Type the denominator into the lower box. Use your keypad to type the denominator, which is the lower number on the fraction. Then, check that your fraction looks right on the calculator screen.[5]
- For instance, if the fraction is 4/5, type "5" into the lower box. Then, check that your fraction accurately depicts 4/5.
[Edit]Using an Online Calculator - Do an online search for a fraction calculator. An online calculator may be the fastest, easiest way to calculate fractions if you're allowed to use the Internet. Type "fraction calculator" in to your favorite browser and click search to find online calculators.[6]
- Insert the first fraction in the top box on the calculator. Most online calculators have 2 boxes so that you can add, subtract, multiply, or divide 2 fractions. Type the first fraction into the top box on the calculator.[7]
- Each online calculator has different instructions. Follow the directions on the online calculator you're using.
- Type the numerator followed by a forward slash and the denominator. Use the keypad on your keyboard to type the top number on your fraction, which is the numerator. Then, hit the forward slash key. Finally, type the bottom number, which is the denominator.[8]
- Select add, subtract, multiply, or divide. Use your cursor to click on the type of operation you want to do. Pick add, subtract, multiply, or divide. Make sure the circle next to your choice is highlighted.[9]
- If the calculator you're using requires you to type in the operation you want to take, use the keypad to insert the operation.
- Put the second fraction in the bottom box. Use the keypad on your keyboard to enter the numerator, then type a forward slash. Type the denominator to complete the fraction.[10]
- Check your fractions before you click the calculate button to make sure you've entered them accurately.
- Click the "calculate" button to get your answer. After you hit the "calculate" button, the calculator will perform the operation for you. This will give you your answer.[11]
- The calculate button might have a slightly different name, depending on the calculator you're using. For instance, it might say "calculate fraction."
[Edit]Turning a Fraction into a Decimal - Divide the numerator by the denominator to get a decimal. The numerator is the top number in the fraction. Type the numerator into your calculator, then push the divide button. Next, type the bottom number into the calculator, which is the denominator. Hit the equal sign to get your decimal.[12]
- For instance, divide 3/4 = .75.
- Any time you see a fraction, it's a form of division.[13]
- Write the integer in a mixed number, followed by the decimal number. Mixed numbers include both an integer and a fraction. The integer will stay the same when you turn the fraction into a decimal. Write the integer in your answer box, then divide the numerator in the fraction by the denominator. Put a decimal point after the integer and write the decimal number you got when you divided the fraction.[14]
- As an example, let's say your mixed number is 2-2/3. You'd divide 2/3 = .67. Write 2.67 for your decimal number.
- Turn 2 fractions into decimals before computing them. If you're adding, subtracting, multiplying, or dividing 2 fractions, convert each of them to a decimal separately using division. Then, use the decimal numbers to calculate an answer.[15]
- As an example, let's say you wanted to add 1/2 + 3/5. You'd first divide 1/2 = .50. Then, divide 3/5 = .60. Finally, add .50 + .60 = 1.10.
[Edit]Writing a Fraction as a Percent - Divide the top number by the bottom number. Treat the fraction bar as a division sign. Type the top number into your calculator, then click divide. Type in the bottom number in the fraction, then click the equal sign. This will give you a decimal number.[16]
- For instance, divide 1/4 = .25.
- Multiple the result by 100 to convert it into a percent. A percent is taken out of 100, so multiplying the decimal by 100 turns it into a percent. Type your decimal into the calculator, then hit the multiply button. Enter 100, then click the equal sign.[17]
- As an example, multiply .25 x 100 = 25.
- You can also just move the decimal point over 2 numbers to the right.
- Place a percent sign after the number to show it's a percent. When you write out the number, put a percent after the number to make it a percent. This will show people that the number is a percentage out of 100.[18]
- For example, you'd write 25%.
- Always write a fraction in the lowest terms when you're recording an answer. For instance, reduce 2/4 to 1/2. Similarly, reduce 5/4 to 1-1/4.

| How to Dice an Onion Posted: 12 Apr 2021 05:00 PM PDT Dicing an onion into small, uniform pieces is important in many recipes so they cook evenly. Luckily, there is an easy way to cut your onion so your knife doesn't slip and so the pieces are all the same size. As long as you have a sharp knife, you'll have onions that are ready for any recipe! [Edit]Dicing the Onion with a Knife - Cut from the top of the onion. The top of the onion, or the stem, is the pointed end of the bulb. Set your onion on a cutting board, and measure down from the top of the stem by about . Use a sharp knife to make a straight cut so you have a flat edge on top of your onion.[1]
- Leave the root on the other side of the onion uncut.
- Halve the onion from top to bottom. Set your onion down so the side you just cut is face down on your cutting board. Place the blade of your knife in the middle of the root on top and cut straight through the onion so you have 2 halves that are the same size.[2]
- Peel back the outer skin from each half of the onion. The outer peel usually has a top layer that's easy to remove and a second layer that's more difficult to pull off. Rip the loose outer peel off the onion and throw it away. Pick the edge of the next peel with your fingernail to separate it from the rest of the onion. Pull the peel back toward the root without removing it completely.[3]
- The peel still attached to the root can be used as a "handle" to make holding onto your onion easier while you cut it.
- Cut straight lines toward the root of the onion. Hold your onion by the peel near its root. Start on one side of the onion, placing the tip of your knife from the root. Make vertical cuts from the root toward the flat edge you cut earlier. Work your way across the onion, spacing each cut the same distance apart from one another.[4]
- The root will help hold your onion in place, so be sure not to cut completely through it.[5]
- Make 2-3 sideways cuts from the flat side. Press down lightly on top of the onion and hold your knife so the blade is parallel to the cutting board. Start cutting into the flat side of onion up from the cutting board. Angle your knife slightly down so you don't cut toward your fingers. Just before you reach the root, pull your knife out of the onion. When you're finished with the first cut, make cuts that are the same distance apart until you reach the top of the onion.[6]
- Work slowly so you don't accidentally cut yourself.
- Slice the onion lengthwise to dice it. Turn your onion so the root is on the same side as your non-dominant hand. Put your fingertips on top of the onion so the side of the knife blade touches your knuckles. Starting on the flat side, cut through the onion. After each cut, move your fingers back so you can guide your knife. Make cuts until you reach the root.[7]
- Make sure all of your cuts are the same distance apart so your pieces are all the same size.
[Edit]Chopping in a Food Processor - Cut the onion in half with a knife. Cut the stem and root off the top and bottom of your onion so you have 2 flat edges. Set the onion upright on one of the flat sides and cut through the middle of it so you have 2 pieces that are about the same size.[8]
- Make sure the chef's knife you use is sharp or else it will be difficult to cut through your onion.
- Remove the outer peel from the onion. Use your finger to tear off the loose outer peel from your onion. Pick at the edge of the peel on your onion with your fingernail to separate it. Pull the peel completely off so the surface feels smooth to the touch.[9]
- If you have trouble separating the peel with your fingernail, scrape it with the edge of your knife to lift it.
- Put the onion halves in your food processor. Take the lid off of your food processor and put the onion halves on opposite sides of the container. Make sure the onions aren't directly on top of the blades since they won't dice as well otherwise. Place the lid back on top of the food processor and secure it in place so it doesn't come off.[10]
- Be careful of the blades while putting your onions into the machine since they are sharp and could cut you.
- Never operate your food processor without the lid.
- Use the "Pulse" button to dice your onions slowly. Press the "Pulse" button once to start chopping your onions. Watch through the container to see how much it chops your onions. Press and hold the button for 2-3 seconds at a time before letting go so you can see how big the pieces are. Keep pulsing the onions until they're as small as you need them.[11]
- Be careful not to pulse your onions too much or else they will turn liquidy and you can't use them in your recipe.
[Edit]Using Best Practices - Pick firm onions without any sprouts or soft spots. Look for black or brown spots on the onion peel to see if they're starting to mold. Avoid buying any onions that have green sprouts growing from them since they are not fresh and are more likely to spoil faster. Look for onions that feel solid and don't have any discoloration.[12]
- Whole onions stay good in your pantry or fridge for up to 3 months.
- Chill the onion in your fridge for 15 minutes before cutting it to prevent crying. Onions release a gas when they're cut open may make you tear up. Put your onion in the fridge or freezer for 15-20 minutes before you want to dice it to help prevent the gas from releasing. That way, you won't get teary-eyed while you're working with it.[13]
- You can also wear kitchen goggles to help prevent any tears.
- Practice safe knife skills. Keep your index finger and your thumb wrapped around the base of the knife and hold the handle securely with the rest of your fingers. Keep the fingers on your other hand in a claw shape so you don't accidentally cut your fingertips while you're chopping. When you make your cut, rock your knife forward to get the cleanest cut.[14]
- Always keep the knife blade pointed away from you so you don't accidentally cut yourself.
[Edit]Warnings - Keep your fingers away from the knife blade so you don't accidentally cut yourself.

| How to Create Study Plans Posted: 12 Apr 2021 09:00 AM PDT Whether you're a university student or simply learning something new on your own, study time is crucial if you want to do well in your classes. With a study plan, the time you need simply becomes a part of your day so you don't have to worry about an exam or deadline sneaking up on you. The process can seem daunting if you haven't made your own study plan before, but never fear! We've compiled all the most useful tips for you to get the most out of your study time. We'll start with advice on how to work studying into your schedule, then give you some bonus tips on how to structure each study session to max out your productivity. [Edit]Carve out time to study every day. - Set aside at least a couple of hours as dedicated study time. If you have a full day of classes and work, you might not have more than an hour or two each day to study. Use the weekend to catch up! If your schedule doesn't leave open a full 2-hour block on any particular day, look for spots where you can sneak in smaller 20-30 minute blocks.[1]
- For example, you might study for an hour in the morning, a half-hour at lunchtime, and another half-hour in the afternoon before work.
- If you're working while going to school, include your study plan on your school schedule and let your manager know that you're not available for work during those times.
[Edit]Schedule backward from exams and deadlines. - Put your exams and deadlines on your calendar when you get your syllabus. If you're taking several classes, you can easily see if you have several exams on the same day or projects due at the same time. Then, plan your study time backward from those dates to make sure you have enough time to get everything ready.[2]
- Plan on getting papers and other assignments done early so you have time to edit and polish them before you turn them in. This also helps you avoid the stress of trying to do the entire thing at the last minute.
[Edit]Include enough study time each week for each class. - The general rule is to study for 3 hours for every credit hour of the class. Use this rule to create your study plan before classes start. As you get into your classes, you might find that some of them require more study time while others require less.[3]
- For example, if you're taking a Spanish class for 3 credit hours, schedule 9 hours of study for that class each week.
- If a subject comes easily to you or you're taking a class that's mostly a review of stuff you already know, you can probably get away with less time studying.
[Edit]Study at around the same time every day. - Your brain will be more focused if you commit to a regular schedule. After a week or two, you'll get in the habit of studying at that time, the same as you get used to having classes at a certain time. If you're going to school full-time, think of your school day as a workday and schedule study time in between classes to get the most out of your day.[4]
- If you have seasonal activities, plan your study schedule around those activities even when they're not going on. For example, suppose you play intramural soccer during the spring, with practice on Mondays and games on Thursdays. Schedule your study time so it doesn't conflict, then you won't have to change your study plan when soccer starts.
[Edit]Use your syllabus to plan each study session. - Set specific tasks to do each study session using action words. Think of your syllabus as a roadmap to guide your study sessions until the end of the course. Note when lectures are and what you're supposed to do to prepare, then add in time to review your lecture notes before you prepare for the next class session.[5]
- For example, suppose you have a history class on Tuesdays and Thursdays. Your instructor assigns reading to prepare for the class. Your study plan might be to read for 1 hour on Monday, review lecture notes for 15 minutes on Tuesday, read for 1 hour on Wednesday, then review lecture notes for 15 minutes on Thursday.
[Edit]Break up larger assignments. - Do smaller parts of larger assignments over a longer period. Working backward from the due date, plan out blocks when you'll work on specific segments of a larger assignment. Use the week of the due date to bring those parts together and do the final polishing of your assignment so it's ready to turn in.[6]
- For example, if you have a research paper due in 3 weeks, you might research the first week, write the first draft the second week, then edit and proofread the week the paper's due.
[Edit]Study the most difficult things first. - Do more challenging things when your mind is fresh. When you sit down to study a subject, start with whatever part is giving you the most trouble. Dedicate as much of your time to that thing as you feel like you need to before moving on.[7]
- If you manage to conquer something that was giving you trouble before, you'll feel more motivated to tackle easier parts of the material.
- While you don't want to completely neglect material you feel confident about, a quick review is usually all you'll need to keep it fresh if you feel like you already know it well.
[Edit]Plan for regular breaks to maintain focus. - Study for 25 minutes then take a 5-minute break. This tactic is known as the Pomodoro Technique and helps you maintain peak focus. When you take your break, though, remember to actually take a real break for the entire 5 minutes. Get up and walk around, do jumping jacks, get a snack, text friends, or watch cat videos on YouTube—whatever you need to give your brain a rest![8]
- This isn't just goofing off—without regular breaks, your brain will internalize less of what you study. Taking frequent breaks helps you get the most out of your study sessions.
- Keeping your study blocks short also helps you stay on task because you know a break is coming up soon. It's easy for your mind to wander if you've been sitting and staring at the same material for an hour.
[Edit]Review as soon after class as possible. - Go over what you covered in class as soon as possible to cement it in your brain. Look over your lecture notes, then try writing a brief summary of what you talked about in class. Think about what you would say if someone asked you what you talked about in class today. Usually, about 15 minutes is sufficient for a review.[9]
- For example, if you have 2 classes on Mondays, Wednesdays, and Fridays, you might plan a half-hour study session on those evenings to go over what you covered in each class that day.
- Go through your notes and fill in any areas that might be hard to understand or difficult to read. For example, if you were writing really fast, your notes might be illegible if you don't go back to them for several weeks.
- Reviewing soon after class can also help you identify concepts you don't understand or questions you might have for your instructor. That way, you can send them an email or take advantage of their office hours to get an answer immediately, rather than waiting until right before the exam.
[Edit]Add a cumulative review every week. - Read through your notes for each class at least once a week. It's easy to forget what you've learned when you're constantly learning new things each week. Creating an outline for your class is a good way to do a cumulative review. Then, all you have to do is go over your outline each week.[10]
- For example, if you're taking 4 classes, you might schedule a 2-hour study block on Saturdays in which you spend 30 minutes doing a cumulative review for each class.
- Cumulative review also helps you understand how the later things you learn build on the earlier things you learned. You'll likely notice new connections between parts of the class that you wouldn't have noticed otherwise.
- This is especially important for classes that have a cumulative final exam. If you've done a cumulative review every week, you'll have a lot less work to do to get ready for that big final.
- Look for blank spaces in your regular schedule that can be used for exam study. In addition to your regular study time, you might want to study more in the week or so before an exam. Instead of taking away from study time for other classes, add more study blocks that you can dedicate to exam preparation.[11]
- For example, suppose you have a chemistry exam coming up. You normally study chemistry for an hour on Mondays, Wednesdays, and Fridays, then for 2 hours on Saturday. If you have free time on Tuesdays and Thursdays, you might add an hour of study on those days the week before the exam.
[Edit]Evaluate your plan regularly and tweak it if necessary. - Increase or decrease study time based on your grades and class performance. If you start to feel like you're really struggling in one class, figure out where you can make more time to study for that class. You might also want to try different study methods if what you're doing isn't working, such as joining a study group or going to the professor's office hours.[12]
- If you had an exam for a class that you thought was easy and you did really well on, you probably don't have to study as much for that one. Take some study time from the easy class and use it for one you find more challenging.
[Edit]Use group study sessions to prepare for exams. - Work with classmates as it gets closer to exam time. If you're weak in one area, chances are there's someone else in the class who's strong in that same area and can help you understand it. If you've got something down, teaching it to someone who doesn't helps you understand it even better.[13]
- In classes where problem-solving and thinking are important, working in groups is an asset because you can learn different ways of thinking and approaching problems that you might not have thought of on your own.
- Even if you don't think you work well in groups, give a study group a chance—especially if it's your first year in university—just to see if you get anything out of it. You can always drop the group if you don't feel like you're getting any benefit from it.
[Edit]Set up a dedicated study area. - Choose a well-lit, comfortable spot where you can focus and concentrate. It's usually better if you always study in the same place and have all of your materials handy so you don't waste any of your precious study time hunting for something. If your study area is outside your own home, you might want to pack up a separate backpack with all of your study tools so you know you'll always have them with you.[14]
- Think about your own needs—everyone's ideal study environment will be different! If you need absolute quiet with no distractions, you might find it best to study in a carrel in the library. But if you need a certain level of ambient noise and movement in the background, a café might be a better choice.[15]
- The right study environment for you will depend on what type of learner you are. For example, if you're a visual learner, you might work best in an environment with a lot of color and brightness. If you're a kinesthetic learner, you might work best in a place where you can get up, move around, and write things down on a whiteboard.[16]
- Studying with a friend or group can help you stay motivated.[17]
- Use short bursts of time between classes to quickly review your notes or go through flashcards.[18]
