What is Fraction Calculator?

A fraction shows part of a whole as one whole number over another, such as 3/4. Working with fractions by hand means finding common bottoms and simplifying, which is easy to get wrong.

What this tool does

Takes two fractions and an operation and shows the answer in lowest terms, as a mixed number and as a decimal. It tells you if you try to divide by zero.

How to use it

  1. Enter the top and bottom of the first fraction.
  2. Choose add, subtract, multiply or divide.
  3. Enter the second fraction and read the answer.

Did you know?

  • To add fractions you first need a common bottom; the least common multiple of the bottoms is the neatest choice.
  • Dividing by a fraction is the same as multiplying by its flip, so รท 2/3 is the same as ร— 3/2.
