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
denominator..  1,2,3,5,6,10,15,30

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
