Question

15 liters of water is to be filled in $\frac{1}{3}$ liters of bottles. How many bottles are required for this Process?

Answer 1

Total quantity of water $=15$ liters
Quantity of each bottle $=\frac{1}{3}$ liter
Number of bottle required $=$ Total quantity of water $÷$ Quantity of each bottle
$=15÷\frac{1}{3}=\frac{15}{1}÷\frac{1}{3}$

Take a reciprocal of the second fraction and multiply with the first fraction as follows,
$=\frac{15}{1}\times \frac{3}{1}$

$=\frac{15\times 3}{1\times 1}$

$=45$
45 bottles are required.
