Answer 2

You need to mix 18 quarts of sparkling water

Explanation:

A recipe for sparkling grape juice calls for
`1(1)/(2) =(3)/(2)` quarts of sparkling water and
`(3)/(4)`quart of grape juice.

Ratio of sparkling water to grape juice =
`(3)/(2):(3)/(4)`

Let the amount of sparkling water be x

We are given that amount of grape juice is 9 quarts

So, Ratio of sparkling water to grape juice x:9

So,
`(3)/(2):(3)/(4)::x:9`

`((3)/(2))/((3)/(4))=(x)/(9)`

`((3)/(2))/((3)/(4)) * 9 = x`

`18= x`

Hence you need to mix 18 quarts of sparkling water
