c and d are not  equivalent rational numbers

Step-by-step explanation:

A)1/4 and -8/-32

1/4 * -8/-8 = -8/-32

when mutiplayed by same numerator and denominator (-8) we get -8/-32

B)-3/4 and 9/-12

-3/4 * -3/-3 = 9/-12

when mutiplayed by same numerator and denominator (-3) we get 9/-12

C)25/30 and 15/18

There is no fraction where there is same numerator and denominator and the answer is  15/18

D)32/56 and 4/14
