Interface Overview

The main screen is divided into three areas:

ℹ️
On iPad and Mac, the step-by-step panel appears alongside the calculator rather than as an overlay, so you can see the working at all times.

Entering Fractions

Fractions are entered using a simple two-step process:

  1. Tap the numerator field and type the top number.
  2. Tap the fraction bar button (─) or swipe down to move to the denominator field, then type the bottom number.

Negative Fractions

To enter a negative fraction, tap the +/− key after entering the numerator. The negative sign applies to the entire fraction.

Whole Numbers

You can mix whole numbers with fractions in a single expression. Enter the whole number part using the digit keys, then tap the fraction button to add a fractional component and create a mixed number.

Basic Operations

Fractions Calculator supports all four standard arithmetic operations:

OperationButtonExampleResult
Addition+¼ + ½¾
Subtraction⅔ − ⅓
Multiplication×⅔ × ¾½
Division÷½ ÷ ¼2

Results are always displayed in their simplest (fully reduced) form automatically. You can turn off auto-simplification in Settings if you want to see the raw result first.

Chaining Calculations

After getting a result, simply tap an operator to continue the chain — the result becomes the first operand of the next calculation. This works exactly like a standard calculator.

Mixed Numbers

A mixed number combines a whole number with a proper fraction, such as 2 ¾. Fractions Calculator lets you enter and display results in mixed number form.

Entering a Mixed Number

  1. Type the whole number part (e.g., 2).
  2. Tap the Mixed button to activate mixed-number mode.
  3. Enter the numerator and denominator of the fractional part.

Switching Display Mode

Tap the Mixed ⇄ Improper toggle in the display area to switch how the result is shown between a mixed number and an improper fraction at any time.

💡
The display mode preference is remembered between sessions. Set it once and the app will always show results the way you like.

Simplifying Fractions

All results are automatically simplified to lowest terms. You can also simplify any fraction on its own:

  1. Enter the fraction you want to simplify.
  2. Tap the Simplify button (the downward-arrow icon).
  3. The simplified fraction is shown in the result area. Tap Steps to see the full working.

The simplification works by computing the Greatest Common Divisor (GCD) of the numerator and denominator and dividing both by it. The step-by-step panel explains this in plain language.

Step-by-Step Solutions

One of the most powerful features of Fractions Calculator is its ability to show every step of the working, making it ideal for learning and checking your work.

Viewing Steps

  1. Perform any calculation.
  2. Tap the Steps button (shown as a list icon) in the toolbar or result area.
  3. The step-by-step panel slides in, showing each stage of the calculation.

What's Shown

Depending on the operation, steps may include:

💡
You can share or copy step-by-step solutions using the Share button at the top of the steps panel — useful for homework or teaching.

Conversions

Fractions Calculator can instantly convert any fraction to several other formats.

ConversionHow to AccessExample
Decimal Tap = Dec or the decimal toggle ¾ → 0.75
Percentage Tap % in the toolbar ¾ → 75%
Simplified form Tap Simplify ⁴⁄₈ → ½
Improper fraction Tap Mixed ⇄ Improper toggle 2 ¾ → ¹¹⁄₄
Mixed number Tap Mixed ⇄ Improper toggle ¹¹⁄₄ → 2 ¾

Conversion results are shown in the display area and are also saved to History.

Calculation History

Every calculation you perform is automatically saved to your History. You can access it any time to review, reuse, or share past results.

Accessing History

Tap the clock icon (⏱) in the toolbar to open the History panel. Entries are listed in reverse chronological order, most recent at the top.

Working with History Entries

iCloud Sync

History syncs automatically across all your devices via iCloud when you're signed in with the same Apple ID. Changes appear on other devices within seconds.
