Fraction Calculator

What this calculator helps you do

Use the fraction calculator to add, subtract, multiply, divide, and simplify fractions in one place. It is useful for schoolwork, recipes, measurements, and any task where decimal answers are less practical than exact fractional results.

How fraction operations work

Some operations need a common denominator first. For example, adding one half and one third becomes three sixths plus two sixths, which equals five sixths.

Worked example

3/4 + 1/8 becomes 6/8 + 1/8 = 7/8. A multiplication example is 2/3 x 9/10 = 18/30 = 3/5 after simplification.
