Question 1(b)

Determine if the following are in proportion:

33, 121, 9, 96

Answer 1

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

Ratio of 33 to 121 = $\frac{33}{121}$ = 3 : 11

Ratio of 9 to 96 = $\frac{9}{96}$ = 3 : 32

Since the simplest form of the ratios 33 : 120 and 9 : 96 are not equal,33, 121, 9, 96 are not in proportion.
