2 cups. You have 4 servings of flour so you need 4 servings of sugar.

Answer:

[tex]2\ cups\ of\ sugar[/tex]

Step-by-step explanation:

we know that

Trina uses [tex]1/2[/tex] cup of sugar and [tex]3/4[/tex] cup of flour in a recipe

so

by proportion

Find how many cups of sugar would she need if she uses [tex]3[/tex] cups of flour

[tex]\frac{(1/2)}{(3/4)}\frac{cups\ of\ sugar}{cups\ of\ flour}=\frac{x}{3}\frac{cups\ of\ sugar}{cups\ of\ flour}\\ \\ x=3*(1/2)/(3/4)\\ \\x=2\ cups\ of\ sugar[/tex]
