How to Use the Fraction Calculator

Enter the numerator and denominator for each fraction, then select the operation you want to perform. The calculator supports addition, subtraction, multiplication, and division.

The result is automatically reduced to its simplest form and is also shown as a decimal when appropriate.

How to Add Fractions

To add fractions with different denominators, first find a common denominator. Then convert each fraction to an equivalent fraction using that denominator and add the numerators.

For example:

1/2 + 1/4 = 2/4 + 1/4 = 3/4

How to Subtract Fractions

Subtracting fractions follows a similar process. Find a common denominator, convert the fractions if necessary, and subtract the numerators.

For example:

3/4 − 1/4 = 2/4 = 1/2

How to Multiply Fractions

To multiply fractions, multiply the numerators together and multiply the denominators together. Then simplify the resulting fraction.

For example:

2/3 × 3/4 = 6/12 = 1/2

How to Divide Fractions

To divide one fraction by another, multiply the first fraction by the reciprocal of the second fraction.

For example:

1/2 ÷ 1/4 = 1/2 × 4/1 = 4/2 = 2

How to Simplify Fractions

A fraction is simplified when the numerator and denominator have no common factor greater than 1.

For example, 6/12 can be simplified by dividing both numbers by 6:

6/12 = 1/2
