Question

A recipe for sparkling grape juice calls for 112 quarts of sparkling water and 34 quart of grape juice.

How much sparkling water would you need to mix with 9 quarts of grape juice?
How much grape juice would you need to mix with 154 quarts of sparkling water?
How much of each ingredient would you need to make 100 quarts of punch?

Answer 1

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
