About this tool

What does Fraction Calculator do?

Add, subtract, multiply or divide two fractions. The workspace keeps the input and result together, making it easy to check the change before you use it elsewhere.

For example, you can add, subtract, multiply or divide two fractions while comparing options or checking a rough estimate.

What you can control

Fraction Calculator gives you direct control over first denominator, operation and second numerator.

How to use Fraction Calculator

  1. 1

    Enter the first numerator carefully and check that the unit or format is correct.

  2. 2

    Set first denominator, operation and second numerator and the remaining options to match the result you need.

  3. 3

    Run Fraction Calculator, check the answer against your inputs, and copy the result if you need it elsewhere.

Tips for a better result

  • Keep the entered figures nearby so you can recheck the Fraction Calculator answer and its assumptions.
  • Change one setting at a time—especially first denominator—so differences are easier to compare.
  • Recheck the inputs and assumptions before using the result for an important decision.
