Alyana has a pizza that is cut into 16 slices. After she and her friends finish eating, there are 4 slices left. If each of them ate 2 slices of pizza, how many people ate the pizza?
16 - 4 = <T>subtract(16, 4)=12 slices of pizza were eaten.
So there were 12/2 = <T>divide(12, 2)=6.0 people eating the pizza.
