Kendra has 5.5 pounds of popcorn and wants to package it equally in 50 bags. How can she use place-value reasoning to find the amount of popcorn to put in each bag?

She has 5.5 pounds and wants to split it into 50 bags.

This is a division problem. She wants to divide 5.5 pound into 50 bag:

5.5 / 50 = 1.1 / 10

As far as "place-value reasoning" goes, she could realize that dividing by 10 is the same thing as moving the decimal place to the left, so:

1.1 / 10

= 0.11 pounds on each bag
