How to Simplify Fractions

  1. Find the greatest common factor (GCF) of the numerator and denominator.
  2. Divide both numbers by the GCF.
  3. Check that the new numerator and denominator share no common factor other than 1.

Example: simplify 12/18. The GCF of 12 and 18 is 6. Divide both: 12 ÷ 6 = 2, 18 ÷ 6 = 3. Result: 2/3.
