Answer:

\(2\ cups\ of\ sugar\)

Step-by-step explanation:

we know that

Trina uses \(1/2\) cup of sugar and \(3/4\) cup of flour in a recipe

so

by proportion

Find how many cups of sugar would she need if she uses \(3\) cups of flour

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