Question

How many containers needed to hold 1 liter of water using 1/3 liter held in identical containers?

Answer 1

3. Because each container holds one third.

Answer 2

Amount of water hold by each identical container =$\frac{1}{3}$ of a liter

Amount of water hold by each identical container =$\frac{1}{3} \times 1$ liter

= $\frac{1}{3}$ liter

Let 'n' be the number of containers that hold 1 liter of water.

According to the question,

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

n =$3 \times 1$

n =3

So, 3 containers are needed to hold 1 liter of water.
