1 1/4 can be turned to 1.25
If 1.25 cups of sugar make 20 cookies, then how many cups of sugar will be needed to make 12 cookies?
Make a proportion.
1.25 / 20 = x / 12
Cross multiply
(1.25)(12) = 20x
15 = 20x
Divide both sides by 20
0.75 = x
0.75 cups of sugar are needed to make 12 cookies.
OR
3/4 cups of sugar are needed to make 12 cookies.
