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?

How many slices of pizza were eaten? ** 16 - 4 = <<16-4=12>>12 slices of pizza were eaten.
How many people ate the pizza? ** So there were 12/2 = <<12/2=6>>6 people eating the pizza.
