Question

Create equivalent ratios

If a lemonade recipe requires 2 cups of sugar for every 6
quarts of lemon juice, how many cups of sugar would be
required for 9 quarts of lemon juice?

Answer 1

3

Explanation:

6 cups require 2 cups

9 cups require-------x

Cross multiplication

9x2 = 6x

18 = 6x

x= 3

Another way to think about:

6 + half of 6 = 9

Then

2+ and half of 2 = 3

6 is 3 times more than 2

9 is 3 times bigger than 3
