Question
Multiply the following fractions.
$\frac{2}{5} \times 5 \frac{1}{4}$
$\frac{2}{5} \times 5 \frac{1}{4}$
✓
Answer
We have, $\frac{2}{5} \times 5 \frac{1}{4}=\frac{2}{5} \times\left(\frac{5 \times 4+1}{4}\right)=\frac{2}{5} \times\left(\frac{20+1}{4}\right)$
$
=\frac{2}{5} \times \frac{21}{4}=\frac{2 \times 21}{5 \times 4}=\frac{42}{20}=\frac{21}{10}
$
$
=\frac{2}{5} \times \frac{21}{4}=\frac{2 \times 21}{5 \times 4}=\frac{42}{20}=\frac{21}{10}
