Question 1(e)

Determine if the following are in proportion:

4, 6, 8, 12

Answer 1

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

Ratio of 4 to 6 = $\frac{4}{6}$ = 2 : 3

Ratio of 8 to 12 = $\frac{8}{12}$ = 2 : 3

Since the simplest form of the ratios 4 : 6 and 8 : 12 are equal,4, 6, 8, 12 are in proportion.
