How many pounds in _ ounces?
Marcie wants to convert 84 ounces to pounds.
She knows that there are 16 ounces in 1 pound.
She decides to call Peppermint Patty for help.
3
The Plan
Peppermint Patty says since there are 16 ounces in a pound, subtract 16 until there is nothing left.
This will tell you how many pounds there are and how many ounces are leftover.
4
Let's Solve!
Start with 84 ounces
84-16= 68, 68-16=52, 52-16=36, 36-16=20, 20-16=4
We subtracted "16" 5 times so there is 5 pounds
There are 4 leftover so there are 4 ounces leftover
5
The solution:
84 ounces= 5 lb 4 oz
We subtracted "16" 5 times
There was 4 leftover
