Sometimes the numerator of a fraction will divide evenly into the denominator. The fraction can be reduced by replacing the numerator with a 1 and dividing the original denominator by the numerator to get a new denominator.

EXAMPLES:

because 4/2 = 2

because 6/2 = 3

Fractions in which the numerator and denominator contain the same factor can also be reduced by removing the common factor from both the numerator and the denominator.

EXAMPLES:

The 3s cancel because they are in both the numerator and the denominator, and you get 2/3

The 7s cancel and you get: 3/4

Reduce these fractions to their lowest terms:
