Question

a recipe for sparkling grape juice calls for 1 1/2 quarts sparkling water and 3/4 quart gape juice. how much sparkling water would you need to make 100 quarts of punch

Answer 1

Sparkling grape juice is made with 1.5 quarts sparkling water and 0.75 quarts grape juice. When these two get mixed we get 2.25 quarts sparkling grape juice

So for 2.25 quarts sparkling grape juice we require 1.5 quarts sparkling water

⇒ For 100 quarts sparkling grape juice we require
`(1.5)/(2.25)` * 100 quarts of sparkling water

⇒ Sparkling water required for 100 quarts of sparking grape juice = 66.67 quarts
