Question

A recipe for sparkling water juice calls for 1 1/2 quarts of sparkling water and 3/4 quart of grape juice

a. how much grape juice would you need to mix with 15/4 quarts of sparkling water

b. how much of each ingredients would you need to make 100 quarts of punch

Answer 1

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
