EXPLANATION
Let's see the facts:
We have ----> 14 dozen of cookies
Each dozen is equal to 12 cookies, so the total number of cookies is:
12 * 14 = 168 cookies
The relationship between cups of pecans and cookies is:
7 1/2 cups of pecans for 12 cookies
Dividing the number of pecans by the numbers of cookies give us the relationship:
Let's transform the mix number into an improper fraction:
7 1/2 = 15/2 = 7.5 cups of pecans
Dividing this by the number of cookies:
(15/2)/168 = 5/112 = 0.04464
Answer: There are 0.04 cups of pecans in each cookie.
