Question

Which of the following shows 12⁄28 written in prime factored form to help in reducing the fraction to simplest form?

Answer 1

In terms of prime factors,
12 = 1 x 12
= 1 x 2 x 6
= 1 x 2 x 2 x 3
28 = 1 x 28
= 1 x 2 x 14
= 1 x 2 x 2 x 7

Therefore

`(12)/(28)= (2*2*3)/(2*2*7) = (3)/(7)`

Answer:
`(3)/(7)`
