A recipe that makes 16 brownies calls for 1/3 nuts. How many nuts are needed to make 24 brownies?

Solution

If 16 brownies require 1/3 nuts, 8 brownies require half of 1/3.

Half of 1/3 = 1/2 × 1/3 = (1 ×1)/(2 ×3) = 1/6

If 8 brownies require 1/6 nuts, then 24 brownies require 3 times 1/6 since 8 times 3 is 24.

3 times 1/6 = 3/1 × 1/6 = (3 ×1)/(1 ×6) = 3/6 = 1/2

Therefore, 24 brownies will require 1/2 nuts
