How to Do Fractions on the iPhone: A Step-by-Step Guide

Doing fractions on your iPhone is easier than you might think. With a few taps, you can perform basic and complex fraction calculations using the built-in calculator app or downloading a specialized fraction calculator app. Whether you’re a student, teacher, or just someone who needs to deal with fractions in everyday life, your iPhone can be a handy tool to get the job done quickly and accurately.

After completing the action, you’ll have the ability to solve fraction problems at your fingertips, making math-related tasks more manageable and less time-consuming.


Remember when you had to use a physical calculator to do fractions, and it always seemed like an uphill battle? Those days are long gone, thanks to the technological marvel that is the iPhone. In today’s world, fractions are no longer a source of frustration but rather a simple task that can be accomplished with a few taps on your smartphone.

This is particularly useful for students who deal with fractions in their math classes, teachers who need to demonstrate calculations, or professionals who use fractions in their work, like carpenters or bakers. The importance of knowing how to do fractions on your iPhone cannot be overstated. It allows for quick calculations on the go, which can be handy in many scenarios. For instance, when you’re cooking and need to adjust a recipe, or when you’re doing some DIY and need to measure materials. Let’s dive into the step-by-step tutorial so you can start crunching those numbers with ease.

How to Do Fractions on the iPhone Tutorial

The following steps will guide you through the process of doing fractions on your iPhone, ensuring you can solve any fraction problems with confidence.

Step 1

Open the Calculator app on your iPhone.
This is the app that comes pre-installed on all iPhones and is typically found on the home screen or in the Utilities folder.

The Calculator app on your iPhone is more powerful than it may appear. While it doesn’t show a fraction button, it can still handle fraction calculations. You just have to know the right way to input the numbers.

Step 2

Input the first fraction.
You can do this by entering the numerator (top number), tapping the division symbol, and then entering the denominator (bottom number).

When inputting the first fraction, make sure you use the division symbol to separate the numerator and the denominator. This tells your iPhone that you’re working with a fraction and not just a simple division problem.

Step 3

Enter the operation.
Choose whether you want to add, subtract, multiply, or divide the fractions by tapping the corresponding symbol.

Remember that the operation you choose will determine how the fractions interact with each other. You can mix and match operations as needed for more complex calculations.

Step 4

Input the second fraction.
Follow the same process as the first fraction by entering the numerator, tapping the division symbol, and then entering the denominator.

If you’re dealing with multiple fractions, you can keep adding operations and fractions in sequence. Just make sure to input each fraction correctly to avoid errors in your calculation.

Step 5

Tap the equals sign.
This will complete the calculation and give you the result of your fraction problem.

Once you tap the equals sign, the Calculator app will display the answer. If it’s not in the simplest form, you may need to simplify the fraction yourself or use a specialized fraction calculator app that provides simplified results.


ConvenienceHaving the ability to do fractions on your iPhone means you can tackle math problems wherever you are, without needing a separate calculator or pen and paper.
SpeedThe Calculator app processes calculations instantly, allowing for quick answers and saving time, especially when compared to manual calculations.
AccuracyiPhones are precise, so you can trust the results of your fraction calculations to be accurate, removing human error from the equation.


Limited FunctionalityThe built-in Calculator app on the iPhone doesn’t have a dedicated fraction button, which might make the process less intuitive for some users.
Simplification RequiredThe Calculator app doesn’t always provide the simplest form of a fraction, so you may have to simplify the result manually.
Learning CurveSome users may need time to get accustomed to inputting fractions on a digital calculator, which could initially slow down the process.

Additional Information

While the built-in Calculator app on your iPhone is a great starting point, there are numerous third-party apps available that cater specifically to fraction calculations. These apps provide additional functionality, such as simplifying fractions, converting fractions to decimals, and more.

Moreover, it’s vital to understand the basics of fractions to verify the results you’re getting from your iPhone. While technology is reliable, having a solid grasp on the math behind the calculations is essential for accuracy and application in real-world scenarios.

Something else to keep in mind is that certain iOS updates bring improvements to the Calculator app, so it’s always a good idea to keep your iPhone updated. This way, you’ll have the latest features and possibly an even better experience with fractions on your iPhone.
