Which pairs of fractions are equivalent? mark all that apply. 8/12 and 2/3

The two fractions that you gave are equivalent... 12 is a common denominator. you have to multiply 3 × 4 to get 12. so if you multiply the same number by the numerator 2× 4 = 8.

2/3 × 4/4 = 8/12

The reason they are equivalent when you multiply by 4/4 is because you are just multiplying by 1 (4/4 = 1). 1 times anything is itself. So the way it looks changes but the value stays the same.

The fraction 8/12 and 2/3 are equivalent on because they are equivalent because you just have to multiply 12 * 2 wishes 24 and 8 * 3 wishes 24 then with them was 3/4 and 20 / 28 walk just have to multiply 4 * 20 and 28 * 3 which 20 * 4 is 80 and 3 * 28 is 84 so no those are not equivalent now 4/5 and 12/16 are not equivalent because 16 * 4 =64 + 5 * 12 + 60 so no they are not equivalent now 7/10 and 21/30 are equivalent because 7 * 30 is 210 and 10 * 21 is 210 times so those are the answers and yes
