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 =  \(\frac{1}{2}\)

                                                                                     = 0.5 cups

she uses the number of cups of flour in a recipe =   \(\frac{3}{4}\)

                                                                                = 0.75 cups

The proportion of sugar and flour she uses =  \(\frac{0.5}{0.75}\)

Let the sugar would be needed for 3 cups of flour = x

Therefore,  \(\frac{0.5}{0.75}\) ×  \(\frac{x}{3}\)

\(x=\frac{1.5}{0.75}\)

x = 2

She would be needed 2 cups of sugar.
