Dean ordered 2 large pizzas that were each cut into 12 slices. His friends Frank and Sammy came over to enjoy some pizza and watch a movie. Dean was hungry and ate half of the Hawaiian pizza. Frank only ate 3 slices of Hawaiian pizza and Sammy ate a third of the cheese pizza. How many total slices were left over? Let's answer step by step:
User
2 pizzas were ordered and had 12 slices each for a total of 2 * 12 = 24 slices. Dean ate 1 / 2 of a 12 sliced pizza so 12 / 2 = 6 slices were left over. Sammy ate 1 / 3 of a 12 sliced pizza so 12 / 3 = 4 slices were left over. Dean ate 6 slices, Sammy ate 4 and Frank had 3 so 6 + 4 + 3 = 13. They started with 24 slices and 13 slices so 24 - 13 = 11 slices left. The answer: 11.
