Question

express the fraction in simplest form 9/12

Answer 1

9/12 dividing both the numerator and the denominator by 3

9/3=3
12/3=4

this reduces down to 3/4

Answer 2

just like they said you find the factors of both of them that they have in common like in this problem ×3 so you divide that 3 with your numerator and your denominator and t gets shorter
9÷3=3
12÷3=4
3/4
