Question

sugar cookies require 2 cups of flour for every 2/3 cups of sugar. how much sugar for 5 cups of flour

Answer 1

Billy, this is the solution to the exercise:

For answering it, we will use the Direct Rule of Three, this way:

Sugar (cups) Flour (cups)

2/3 2

x 5

____________________________

x * 2 = 5 * 2/3

2x = 10/3

Dividing by 2 at both sides:

2x/2 = 10/3 / 2

x = 10/3 * 1/2

x = 10/6

x = 1 2/3 (simplifying)

We will need 1 2/3 cups of sugar for 5 cups of flour
