Question

Multiply the following fractions: $\frac{2}{5}\times 5\frac{1}{4}$

Answer 1

Step 1: Convert the mixed fraction to an improper fraction and then multiply.

$\begin{array}{c}\frac{2}{5}\times 5\frac{1}{4}=\frac{2}{5}\times \frac{21}{4}\\ =\frac{21}{10}\end{array}$

Step 2: Convert $\frac{21}{10}$into a mixed fraction.

Divide $21$by $10$,we get;

$10221-\underline{2}\underline{0}1$

$\therefore \frac{21}{10}=2\frac{1}{10}$

Hence the product of $\frac{2}{5}\times 5\frac{1}{4}$is $2\frac{1}{10}$.
