Question

a recipe needs 4/5 cup(s) of sugar for every 3 cups of flour. if you plan to use 7 1/2 cups of flour, how much sugar will you need?

Answer 1

2 cups of sugar

Explanation:

Set up a proportion where x is the amount of sugar for 7.5 flour cups

`(3)/(0.8)` =
`(7.5)/(x)`

Cross multiply and solve for x:

3x = 6

x = 2

So, you will need 2 cups of sugar
