A tank had 500 l of water. A family use one-fifth of the water. How much water was left?

Given :

The volume of water in the tank $= 500 L$

The fraction of water used by the family $= \frac{1}{5}$

To do :

We have to find the water left.

Solution :

Volume of water used by the family $= \frac{1}{5} (500) L = 100 L$

Therefore,

Volume of water left in the tank $=$ Total volume $-$ Volume used $= 500 L - 100 L = 400 L$.

The water left is 400 L.
