Question

A jar of crunchy peanut butter contains 1.4 3 KG of peanut butter if you use 80% of the peanut butter for a sandwich how many ounces of peanut butter did you take out of the container?

Answer 1

First you want to calculate 80% of 1.43 Kg, which is. .80×1.43 = 1.144kg

Change this Kg into grams and then to ounce using dimensional analysis

1.144kg ×1000gm/ 1kg × 1oz./ 28.35gms = 40 ounce of peanut butter has been taken out.
