Exercise 43 Page 267

Use a conversion factor. How many ounces are there in one pound?

132oz

Practice makes perfect

Since there are 16 ounces (oz) in every 1 pound (lb), we can write this as the following conversion factor. 16oz/1lb If we multiply 8.25lb by this conversion factor, we can get the measurement in ounces.

8.25lb* 16oz/1lb

MoveLeftFacToNum

a*b/c= a* b/c

8.25lb * 16oz/1lb

Cross out common factors

8.25lb* 16oz/1lb

Simplify quotient

8.25 * 16oz/1

a/1=a

8.25 * 16oz

Multiply

132oz

8.25 pounds is equal to 132 ounces.
