Answer :
[tex]\frac{7}{8}\text{ cups of sugar}[/tex]
Here, we want to get the number of cups of sugar
From what we have, we can see that the ratio between the cups of sugar and cups of flour is 1/2 ratio 1 which is 1:2
So, for every cup of sugar, there would be 2 cups of flour
To get the cups of sugar given the cups of flour, we simply divide the cup of flour by 2
Mathematically, we have this as;
[tex]\begin{gathered} 1\frac{3}{4}\text{ divided by 2} \\ =\text{ }\frac{7}{4}\times\frac{1}{2}\text{ = }\frac{7}{8} \end{gathered}[/tex]
