Exercise 57 Page 121

Can you break down the numerator and denominator into prime factors?

2y/7

Practice makes perfect

To write the fraction in its simplest form, we begin by trying to break down the numerator and denominator into prime factors. 2xy/7x=2* x* y/7* x Both numbers share the factor x, so that is the greatest common factor (GCF) of the fraction. Reducing the numerator and denominator by the GCF will give us the fraction's simplest form.

2xy/7x

a/b=.a /x./.b /x.

2xy/x/7x/x
