Question

Determine if the following are in proportion.
32, 48, 70, 210

Answer 1

$\large{\bold{\underline{Solution:}}}$


32 : 48 = $\large{\bold{ \frac{\cancel{\sf32}}{\cancel{\sf48}} = \frac{2}{3} = 2 : 3}}$

70 : 210 = $\large{\bold{ \frac{\cancel{\sf70}}{\cancel{\sf210}} = \frac{1}{3} = 1 : 3}}$

Since $\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bold{32 : 48 ≠ 70 : 210}$

Therefore, $\bold{32, 48, 70, 210}$ are not in proportion.
