Question

$\text{Susan drinks}\frac{4}{5}L\text{of milk in 1 day.}$
In 4 days, she drinks of milk.

• A. $\frac{8}{5}L$
• B. $\frac{12}{5}L$
• C. $\frac{16}{5}L$
• D. $\frac{20}{5}L$

Answer 1

The correct option is C $\frac{16}{5}L$

$\text{Amount of milk taken by Susan in 1}$
$\text{day =}\frac{4}{5}L$

$\text{To find the amount of milk she drank}$
$\text{in}4\text{days, multiply}4\text{by}\frac{4}{5}.$

$\text{So, the answer is}=4\times \frac{4}{5}$
$=\frac{16}{5}L$

Let's understand this better with the help of the fraction bar.

The steps are:

$\text{1. Like repeated addition, make 4}$
$\text{fraction bars with}\frac{4}{5}.$

$\text{2. Then add the number of blocks}$ $\text{having}\frac{4}{5}\text{in all the 4 bars}.$


$\text{Since there are 16 blocks containing}\frac{1}{5}$
$\text{each, thus}4\times \frac{4}{5}=\frac{16}{5}.$

$\text{Hence, Susan drank}\frac{16}{5}L$
$\text{of milk in}4days.$
