Exercise 41 Page 829

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

3/7

Practice makes perfect

To write the ratio in its simplest form, we begin by trying to break down the numerator and denominator into prime factors. 18/42=3* 2 * 3/7* 2* 3 Both numbers share the factors 2 and 3, the product of which is 6. This is the greatest common factor (GCF) of the ratio. Reducing the numerator and denominator by the GCF will give us the ratio's simplest form.

18/42

a/b=.a /6./.b /6.

18/6/42/6
