Question

A recipe for oatmeal raisin cookies is shown. If you only want to make 9 cookies (0.75 of a dozen), how much cooking oats do you need?

1.125 cup
1.33 cup
0.75 cup
1.50 cup

Answer 1

0.75 cups of cooking oats would be needed.

From the recipe given :

• 1.5 cookies = 1.5 cooking oats

For 0.75 dozen of cookies, x cups of cooking oats

Now we have :

1.5 = 1.5

0.75 = x

cross multiply

1.5x = 1.5 × 0.75

x = (1.5 × 0.75) / 1.5

x = 0.75

Hence, 0.75 cups of cooking oats would be needed.
