How to use the fraction calculator

  1. Type two fractions — 3/4, mixed numbers like 2 1/3, or decimals.
  2. Choose +, −, × or ÷ — the answer appears simplified, as a mixed number and as a decimal, with the working step.
  3. Use the converter below to simplify a fraction or turn a decimal into a fraction.

Great for homework, recipes (doubling 2/3 cup), DIY measurements in inches and checking a child’s maths. Answers are always reduced to lowest terms using the greatest common divisor.
