Question

Write the following ratio in descending order:
$4:7,5:14,9:42,7:21$

Answer 1

Given that,

$4:7,5:14,9:42,7:21$

$\begin{array}{c}\frac{4}{7}=0.71\\ \frac{5}{14}=0.35\\ \frac{9}{42}=0.21\\ \frac{7}{21}=0.33\end{array}$

Then,

We get decreasing order is $\frac{4}{7}>\frac{5}{14}>\frac{7}{21}>\frac{9}{42}$
