Given:
To make 1/2 batch of rolls, it takes 5/4 cups of flour
let To make 1 batch of rolls, it takes x cups of flour
so, using the ratio and proportions to find x
[tex]\frac{1}{2}\colon1=\frac{5}{4}\colon x[/tex]Solve for x:
[tex]x=\frac{5}{4}\cdot2=\frac{5}{2}[/tex]so, the answer will be 5/2 cups of flour
