Why it works

A fraction stays equal when you divide the numerator and denominator by the same nonzero number. Using the greatest common divisor removes every common factor in one step.

Common mistakes

  • Forgetting that a negative denominator should be rewritten with the negative sign in the numerator.
  • Reducing only the numerator or only the denominator.
  • Stopping before you divide by the greatest common divisor.

Worked examples

Simplify 18/24

18/24 = 3/4 because the GCD is 6.

Simplify 15/4

15/4 is already reduced, and as a mixed number it is 3 3/4.
