Question

2.

Hollyville Elementary is having a pizza party. The school secretary plans on ordering 25 pizzas. There are 10 classes in the school. If each class is given 2 1/2pizzas, is 25 pizzas enough for the entire school? If so, how much pizza, if any, will be left over? If not, how many more pizzas will they need?

Answer 1

25 is enough and there will be no pizza left over.

Explanation:

We can multiply the 2 1/2 pizza across 10 classes to see how much pizza we need and if if 25 is enough.

An easy way to do this is to turn 2 1/2 into a decimal then multiply by 10 like that.

2 1/2 = 2.5

2.5 × 10 = 25 pizzas

25 is exactly enough with no pizza left over.
