Here, we have given a fraction and a whole number. To multiply a fraction by a whole, we multiply the numerator of the fraction by the whole number and keep the denominator unchanged.
The given fraction is $1 \frac{4}{5}$ and the given whole number is $2$ .
Converting, the mixed fraction $1 \frac{4}{5}$ into improper fractions.
we have, $1 \frac{4}{5} = \frac{5 \times 1 + 4}{5} = \frac{5 + 4}{5} = \frac{9}{5}$
Now, multiplying $\frac{9}{5}$ and $2$ , we have
$\frac{9}{5}$ $\times$ $2$ $= \frac{9 \times 2}{5}$ [multiplying numerator of the fraction and whole number]
$=$ $\frac{18}{5}$
Therefore, $1 \frac{4}{5}$ $\times$ $2$ $=$ $\frac{9}{5} \times 2$ $=$ $\frac{18}{5}$
