Colleen is making a batch of 48 cookies. She's going to add 108 chocolate chips and one-third as many M&Ms to the whole batch. What are the average number of chocolate pieces in each cookie?
Thoughts? Step-by-step reasoning:
First find the total number of M&Ms: 108 chocolate chips / 3 chocolate chips / 1 M&M = 36 M&Ms. Then add that number to the number of chocolate chips to find the total number of pieces of chocolate: 36 M&Ms + 108 chocolate chips = 144 chocolates. Then divide the total number of chocolates by the number of cookies to find the number of pieces of chocolate per cookie: 144 chocolates / 48 cookies = 3 chocolates / cookie.
Thus, the answer is 3.
