Question 49

Which ratio is larger 10 : 21 and 21 : 93?

Answer 1

Given, ratios are 10 : 21 and 21 : 93
$\frac{10}{21}$ and $\frac{21}{93}$ [by cross multiplication]

We know that if $\frac{a}{b}$ and $\frac{c}{d}$ are two ratios and $ad>bc$, then $\frac{a}{b}>\frac{c}{d}$
$10\times 93$ = 930 and $21\times 21$ = 441

Clearly, 930 > 441
Hence, 10 : 21 > 21 : 93
$\therefore$ 10 : 21 is larger than the ratio 21 : 93
