A fraction calculator adds, subtracts, multiplies and divides fractions and gives the result as both a fraction and a decimal, automatically simplified to its lowest terms.

The maths

  • Add / subtract: use a common denominator
  • Multiply: numerator × numerator, denominator × denominator
  • Divide: multiply by the reciprocal
  • Simplify: divide top and bottom by their greatest common divisor

Examples

  • 3/4 + 2/3 = 17/12 = 1 5/12 = 1.4167
  • 3/4 × 2/3 = 6/12 = 1/2
  • 3/4 ÷ 2/3 = 9/8 = 1 1/8

Frequently asked questions

Can I use improper fractions?

Yes. Enter any numerator and denominator; the calculator handles improper fractions and shows the decimal too.

Why is the result simplified?

Simplifying a fraction (dividing top and bottom by their greatest common divisor) makes it easier to read and compare — 6/12 becomes 1/2.

Just for the giggles, much love.
