Ounces and Pounds

Let's practice!

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.

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.

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

The solution:

• 84 ounces= 5 lb 4 oz

• We subtracted "16" 5 times

• There was 4 leftover

Let's try more!

• 26 ounces= _ lb _oz

• 32 ounces= _ lb _ oz

• 70 ounces= _ lb _ oz

• (Instead of subtracting 16 each time, you can use multiplies of 16: 16, 32, 48, 64, 80, 96, 112, 128)

• 120 ounces= _ lb _ oz
