Answer:

a) 6 cups

Explanation:

We can use a ratio for this:

sugar : flour

2 : 3

x : 9

2 3

--- = ---

x 9

Cross multiply:

2 (9) = 3x

18 = 3x

6 = x

x = 6

To double-check, you can plug the value back into the ratio and make them fractions, then simplify to see if it gets the original amount. Here's what I'm talking about:

2 : 3

x : 9 ======> 6 : 9


(6)/(9) (/3)/(/3) = (2)/(3)
