Key Features

How to Use the Fraction Calculator

Step 1: Enter Your Fractions

Input the numerator and denominator for both fractions. The numerator is the top number, and the denominator is the bottom number. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator.

Step 2: Choose an Operation

Select one of the four mathematical operations:

• Addition (+) - Add two fractions together
• Subtraction (−) - Subtract the second fraction from the first
• Multiplication (×) - Multiply two fractions
• Division (÷) - Divide the first fraction by the second

Step 3: Calculate and View Results

Click the "Calculate" button to see your results. The calculator will display:

• The simplified fraction result
• Mixed number format (if applicable)
• Decimal equivalent
• Step-by-step solution showing how the answer was calculated

Understanding Fraction Operations

Adding and Subtracting Fractions

To add or subtract fractions, you need to find a common denominator. The calculator does this automatically by multiplying the denominators together and adjusting the numerators accordingly. For example:

1/4 + 2/3 = (1×3 + 2×4) / (4×3) = 11/12

Multiplying Fractions

Multiplying fractions is straightforward - simply multiply the numerators together and the denominators together. The calculator then simplifies the result:

2/3 × 3/4 = (2×3) / (3×4) = 6/12 = 1/2

Dividing Fractions

To divide fractions, multiply the first fraction by the reciprocal (flip) of the second fraction:

2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9

Simplifying Fractions

Simplifying a fraction means reducing it to its lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD). Our calculator performs this automatically for all results.

Fraction Calculator Examples

Example 1: Adding Fractions

Problem: 1/2 + 1/3

Solution: (1×3 + 1×2) / (2×3) = 5/6

The result is already in its simplest form.

Example 2: Subtracting Fractions

Problem: 3/4 − 1/2

Solution: (3×2 − 1×4) / (4×2) = 2/8 = 1/4

The fraction simplifies from 2/8 to 1/4.

Example 3: Multiplying Fractions

Problem: 2/5 × 3/7

Solution: (2×3) / (5×7) = 6/35

This fraction is already in its simplest form.

Example 4: Dividing Fractions

Problem: 5/6 ÷ 2/3

Solution: 5/6 × 3/2 = 15/12 = 5/4 = 1 1/4

The result can be expressed as an improper fraction (5/4) or mixed number (1 1/4).

Frequently Asked Questions

Tips for Working with Fractions

Always Simplify Your Answers

After performing any fraction operation, always simplify your result to its lowest terms. This makes the fraction easier to understand and use in further calculations.

Double-Check Your Denominators

Never use zero as a denominator - this creates an undefined value. Always ensure your denominators are non-zero whole numbers.

Convert Between Formats

Understanding the relationship between fractions, decimals, and percentages is valuable. Our calculator shows all three formats to help you see these connections.

Practice Mental Math

While calculators are helpful, practicing basic fraction operations mentally improves your mathematical intuition and problem-solving skills.
