Answer 1

Answer:you would need 18 quarts of sparkling water to mix with 9 quarts of grape juice

Explanation:

1 1/2 ---------> 3/4

x --------------> 9

We clear the value of x:

x = ((9) / (3/4)) * (1 1/2)

Rewriting we have:

x = ((9) * (4/3)) * (1 1/2)

x = (36/3) * (1 1/2)

x = (12) * (1 1/2)

x = (12) * (3/2)

x = 18

Answer:

you would need 18 quarts of sparkling water to mix with 9 quarts of grape juice

Answer 2

Answer: We need to mix 18 quarts of sparkling water with 9 quarts of grape juice.

We need to mix 1.875 quarts of grape juice with 3.75 quarts of sparkling water.

Given: A recipe for sparkling grape juice calls for 1.5 quarts of sparkling water and .75 quart of grape juice.

Since, for recipe of sparkling grape juice , they should be used in same proportion.

Let x be the amount of sparkling water need to mix with 9 quarts of grape juice, then

`(x)/(9)=(1.5)/(0.75)\\\Rightarrow\ x=(1.5*9)/(0.75)\\\Rightarrow\ x=18`

We need to mix 18 quarts of sparkling water with 9 quarts of grape juice.

Let y be the amount of grape juice need to mix with 3.75 quarts of sparkling water, then

`(3.75)/(y)=(1.5)/(0.75)\\\Rightarrow\ y=(3.75*0.75)/(1.5)\\\Rightarrow\ y=1.875`

We need to mix 1.875 quarts of grape juice with 3.75 quarts of sparkling water.
