Ryan is planning a party for 138 people.paper plates are sold in packs of 12.how many packs of paper plates does ryan need to buy so that each guest has a plate?

he would have to buy 12 packs

Step-by-step explanation:

138/12=11.5

The person is traveling 30 mph.

The car is traveling 45 mph.

Just mulitply 15 x 3 and 10 x 3.

Let’s break the numbers down.

10 + 5 = 15. So we can break 15 down like how you add 15.

10 x 3 = 30.

5 x 3 = 15.

Let’s add 30 and 15 together.

30 + 15 = 45.

Let’s now multiply 10 and 3.

10 x 3 = 30.

I hope this helped!
