How the fraction calculator works

Calculate with two integer fractions and view an exactly reduced improper and mixed-number result.

Method and assumptions

Figur adds, subtracts, multiplies, or divides two integer fractions with exact big-integer arithmetic; it normalizes the sign and reduces numerator and denominator by their greatest common divisor.

  • Numerators and denominators are integers; denominators cannot be zero.
  • Division requires the second fraction not to equal zero.
  • The result is presented as a reduced improper fraction and, when applicable, a mixed number.

Worked example

Frequently asked questions
