Question

Convert 5 1/4 lb to oz.

Answer 1

The conversion factor for lb to oz is

`1lb=16oz`

I will put the pounds first in terms of the improper fraction. We have

`5(1)/(4)=(21)/(4)`

Using the conversion factor to convert lb to oz, we have

`(21)/(4)lb*(16oz)/(1lb)=(21\cdot16)/(4)=(21\cdot4)/(1)=84oz`

Hence, 5 1/4 lb is equal to 84 oz.

Answer: 84 oz
