Answer 1

12/28
If we divide numerator & denominator by 4 we will get 3/7 and this is the answer of 12/28 in prime factor. Answer A

Answer 2

`(2 \cdot 2 \cdot 3)/(2 \cdot 2 \cdot 7)`

Explanation:

`(12)/(28)`

we need to find the options in prime factored form to help in reducing the fraction to simplest form

prime factors for 12 is 2 times 2 times 3

prime factors for 28 is 2 times 2 times 7

LEts replace all the factor in the fraction

`(12)/(28)=(2 \cdot 2 \cdot 3)/(2 \cdot 2 \cdot 7)`
