Simplifying (reducing) a fraction means finding the smallest equivalent fraction. Divide both the numerator and denominator by their greatest common factor (GCF).
Simplify 12/18: GCF(12, 18) = 6. Divide both by 6: 12÷6 = 2, 18÷6 = 3. Result = 2/3.
Simplified fractions are easier to read, compare, and use in calculations. Always reduce fractions in final answers for math homework, recipes, and measurements.
