Ivan, Bella, and Ian agreed to share a pizza which was cut into 10 slices. Ivan ate 40% of the pizza. How many slices did he eat?

4 slices

Step-by-step explanation:

Note: * means to multiply

We know there are 10 slices and that Ivan ate 40%.

First turn 40% to a decimal

40% =.40

Next, multiply 10 by. 40

10 *.40 = 4

So Ivan ate 4 slices.
