Number of oatmeal cups = [tex]3\frac{1}{2}=\frac{7}{2}[/tex] cups
Number of cups of milk needed for 7/2 cups of oatmeal = [tex]8\frac{3}{4}[/tex]
=[tex]\frac{35}{4}[/tex] cups
Hence, number of cups of milk used of 1 cup of oatmeal =
[tex]\frac{\frac{35}{4}}{\frac{7}{2}}[/tex]
=[tex]\frac{35}{4}\times \frac{2}{7}[/tex]
=[tex]\frac{5}{2}[/tex] cups
Or in mixed fraction it is = [tex]2\frac{1}{2}[/tex] cups
