Pat is having a picnic with her family. She has 42 cookies. She also has 63 pieces of candy and 21 brownies. There are 7 people in her family. If each person gets the same number of each dessert, how much will each person get? Let's think first. Chain of thought:
Each person gets 42 cookies / 7 people = 6 cookies. Each person gets 63 pieces of candy / 7 people = 9 pieces of candy. Each person gets 21 brownies / 7 people = 3 brownies. Each person will get 6 + 9 + 3 = 18 desserts.
Therefore, the answer is 18.
