Answer:

21 : 24 = 7 : 8

Step-by-step explanation:

We're given two equivalent ratios in which one of the denominator is missing.

We know that, Equivalent ratios can be found by dividing or multiplying both the numerator and denominator by same number.

21 : 24 = 7 : 8.

This is simple mathematics, However we can solve by cross multiplication.

Let the unknown denominator be x.

21 : 24 = 7 : x

21 x = 24 × 7

x = 24/3

x = 8

Therefore, The missing number is 8.
