a recipe for sparkling grape juice calls for 1 1/2 quarts of sparkling water and 3/4 quarts for grape juice, how much of each ingredient would you need to make 100 quarts of punch?

Answer:
Step-by-step explanation:
The ratio of sparkling water to grape juice is ...
(1 1/2 quarts) : (3/4 quarts) = (3/2) : (3/4) = 2 : 1
So, the amount sparkling water in the total volume is 2 : (2+1) = 2/3 of the total volume. For a volume of 100 quarts, the sparkling water content is ...
2/3 · 100 quarts = 66 2/3 quarts
Then the grape juice content is ...
1/3 · 100 quarts = 33 1/3 quarts
