Question

A recipe for cookies calls for a quarter cup if milk for every 12 cookies. If we want to make 30 cookies, how much milk are we going to need?
a.) 1 cup
b.) 1/4 cup
c.) 2 cups
d.) 5/8 cup
e.) 1/16 cup
I know the answer is D but how did they get the answer? PS. I have problems with my internet so if I disconnect I'll be trying to connect again as fast as I can. Sorry if I make anyone wait.

Answer 1

The quantity of milk needed for each cookie is found by dividing a quarter by 12:
\[amount\ per\ cookie=\frac{\frac{1}{4}}{12}\ cup\]
Amount of milk for 30 cookies is
\[\frac{\frac{1}{4}}{12} \times 30=\frac{30}{4\times12}=\frac{30}{48}\ cup\]
Now you just need to simplify the fraction 30/48
