Question

What value of q makes the equation true 25/q = 5/8

A 30
B 35
C 40
D 45

Answer 1

We can figure this out by applying proportionality.

25/5 = 5.

We know the multiplier is 5 between the fraction on the right and the fraction on the left, so we need only to multiply 8 by 5.

8 * 5 = 40.

Your answer is C.
