Question

The ratio of milk to water in a container is 5 : 1 by volume. If the total volume of the mixture is 9 litres, find the volume of water in it.

Answer 1

5+1=6.
6=9 litres.
1=9/6=1.5 litres.
5=(1.5×5)=7.5 litres.--------- Unnecessary.
The volume of water is 1.5 litres.

Answer 2

Volume of water in a mixture= 1.5 l

Step-by-step explanation:

Given,

Ratio of milk and water in the mixture = 5:1

Total Volume of mixture = 9 l.

To find ,

the volume of water in mixture

Let Volume of water = 1x

Volume of milk = 5x

according to question,

5x+x = 9

⇒6x = 9

⇒$x = \frac{9}{6}$

            = 1.5 l

Hence,volume of water in a mixture= 1.5 l
