Question

Four pizzas were ordered for a company lunch. During the lunch, 75% of the pizzas were eaten. If each pizza had 8 slices, how many slices of pizza were NOT eaten during the lunch? A. 16 B. 8 C. 4

Answer 1

See below.

Explanation:

If 75% of the 4 pizzas were eaten, then 25% were NOT eaten, right?

25% is just one-fourth, so 1 whole pizza was left. (One-out-of-four, one-fourth.)

And since each pizza had 8 slices, 8 slices were left.

But they made this one easy. More generically, you'd want to start with how many slices of pizza there were to begin with:

4 pizzas x 8 slices/pizza = 32 slices

75% were eaten, so 25% were NOT eaten:

0.25 x 32 slices = 8 slices NOT eaten
