Question 1(d)

Determine if the following are in proportion:

32, 48, 70, 210

Answer 1

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

Ratio of 32 to 48 = $\frac{32}{48}$ = 2 : 3

Ratio of 70 to 210 = $\frac{70}{210}$ = 1 : 3

Since the simplest form of the ratios 32 : 48 and 70 : 210 are not equal,32, 48, 70, 210 are not in proportion.
