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

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}x=

6

9

= 1.5 l

Hence,volume of water in a mixture= 1.5 L
