1. You have that:
-The jar of crunchy peanut butter contains 1.35 kilograms of peanut butter.
<span>
-You use 8.0 % of the peanut butter.
</span>
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
H<span>ow many ounces of peanut butter did you take out of the container?</span>
The answer is: 3.80 ounces
X=9.9 I believe (sry if I’m wrong)
