#1(1)/3# cups

Explanation:

This is a ratio question. If we are comparing the ratios, we could say #24/36 = x/2# where x = the amount of sugar to make 24 cookies.
We can multiply both sides by 2 to cancel the 2 on the right, making #(24(2))/36 = x#.
Simplify this and we get #48/36# and eventually #4/3# or #1(1)/3#.
