Answer 1

3/4 is not equivalent to 1/2

2/3 is not equivalent to 5/8

Answer 2

5/9 is not equivalent to 5/8

1/2 is not equivalent to 1/4

Explanation:

Two fractions are equivalent when the product of one's numerator and the other's denominator is equal to the product of one's denominator and the other's numerator. Then, 1/2 is equivalent to 2/4 because 1*4 = 2*2

On the other hand:

5/9 is not equivalent to 5/8 because 8*5 ≠ 9*5

1/2 is not equivalent to 1/4 because 1*4 ≠ 1*2
