Answer :
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]
