Question

A jar of crunchy peanut butter contains 1.35 kg of peanut butter. if you use 8.0 % of the peanut butter for a sandwich, how many ounces of peanut butter did you take out of the container?

Answer 1

1. You have that:

-The jar of crunchy peanut butter contains 1.35 kilograms of peanut butter.

-You use 8.0 % of the peanut butter.


2. You must convert 1.35 kilograms to ounces, as below:


1 kilogram=35.2739 ounces

=(1.35 kilogram)(35.2739 ounces/1 kilogram)
=1.35x35.2739 ounces
=47.61 ounces


3. Then, you have:

47.61 ounces-----100%
x-----8%

8%/100=0.08
100%/100=1

x=(0.08x47.61 ounces)/1
x=3.80 ounces

How many ounces of peanut butter did you take out of the container?

The answer is: 3.80 ounces
