SOLUTION
From the diagram given in the question,
[tex]\frac{3}{4}\text{cups of sugar requires 3 cup of water }[/tex]Therefore, using the principle of ratio,
[tex]\begin{gathered} \frac{3}{4}\text{cups sugar=3cups of water} \\ \text{Then} \\ 1\text{ cups of sugar will require} \\ \frac{1\times3}{\frac{3}{4}} \end{gathered}[/tex]Hence
[tex]\begin{gathered} 3\frac{.}{.}\frac{3}{4}=3\times\frac{4}{3}=4 \\ 4\text{cups } \end{gathered}[/tex]Therefore
1 cup of sugar will require 4 cups of water
Answer ; 4 cups of water
