Answer :
Trina uses 1/2cup of sugar and 3/4 cup of flour in a recipe.
Let's find out how many cups of sugar would she need if she uses 3 cups of flour:
=>1/2 = 3/4
=>0.5 = 0.75 = x = 3
=> 3 * 0.5 = 1.5
=> 1.5 / 0.75 = 2
Thus, 2 cups of sugar = 3 cups of flour.

Answer:
2 cups of sugar
Step-by-step explanation:
Trina uses the number of cups of sugar in a recipe = [tex]\frac{1}{2}[/tex]
= 0.5 cups
she uses the number of cups of flour in a recipe = [tex]\frac{3}{4}[/tex]
= 0.75 cups
The proportion of sugar and flour she uses = [tex]\frac{0.5}{0.75}[/tex]
Let the sugar would be needed for 3 cups of flour = x
Therefore, [tex]\frac{0.5}{0.75}[/tex] × [tex]\frac{x}{3}[/tex]
[tex]x=\frac{1.5}{0.75}[/tex]
x = 2
She would be needed 2 cups of sugar.
