There is a group of 18 people who are ordering pizza. If each person gets 3 slices and each pizza has 9 slices, how many pizzas should they order?
Thoughts? Step-by-step reasoning:
Each person eats 3 slices of pizza, the group in total eats 18 x 3 = 54 slices. There are 54 slices in 54 / 9 = 6 pizzas.
Thus, the answer is 6.
