Simplify a Fraction - Arithmetic Step by Step

Reduce 18/24 to lowest terms. First find GCD(18, 24) = 6, then divide both numerator and denominator by 6. The result, 3/4, cannot be reduced further because GCD(3, 4) = 1.

18/24

step: GCD of 18 and 24 is 6
step: 18 ÷ 6 = 3
step: 24 ÷ 6 = 4
step: simplify: 18/24 = 3/4

lowest-terms A fraction is in lowest terms when its numerator and denominator share no common factor greater than 1. Dividing both by their GCD does this in one step. Always check: if GCD = 1, you are done.
