Question

A recipe for raspberry jelly calls for 5 cups of raspberry juice and 2 1/2 cups of sugar. Find the amount of sugar needed for 6 cups of the juice?

Answer 1

The requirement of sugar for 5 cups of raspberry juice = 2 1/2 cups = 5/2 cups

The requirement sugar for 1 cup of  raspberry juice = (5/2 + 5) cups

= (5/2 x 1/5) cups = 1/2 cups

Thus, the requirement of sugar for cups of the raspberry juice = 6 x 1/2 cups = 3 cups
