Question

$\frac{1}{7}$ of $\frac{21}{5}$ =_____.

Answer 1

$\frac{1}{7}$ of $\frac{21}{5}$ is nothing but $\frac{1}{7}\times \frac{21}{5}$.

So, we will multiply numerator of one fraction by the numerator of other fraction and denominator of one fraction by the denominator of other fraction.

So, $\frac{1}{7}\times \frac{21}{5}$ = $\frac{1\times 21}{7\times 5}$ = $\frac{3}{5}$
