Question

Determine if the following are in proportion:

24, 28, 36, 48

Answer 1

If two ratios are equal, we say that they are in proportion.

Ratio of 24 to 28 = $\frac{24}{28}$ = 6 : 7

Ratio of 36 to 48 = $\frac{3}{4}$ = 3 : 4

Since the simplest form of the ratios 24 : 28 and 36 : 48 are not equal,24, 28, 36, 48 are not in proportion.
