Fractions in lowest terms (simplifying fractions)
A fraction is in lowest terms when the numerator and
denominator have no common factor other than 1.
Divide the numerator and denominator by their
greatest common factor.
step 1: list the factors of the numerator.
step 2: list the factors of the
step 3: find the greatest common factor (GCF)
The GCF of both 12 and 30 is 6
Divide both the numerator and the denominator
by the GCF 6
The greatest common factor is the largest number that can be
divided by the numerator evenly. In this case the number is 6
