The Milk Problem
You are a 12 year old boy living in the United States. You are a very picky eater and one day your mom made you something you didn't like for dinner. Now usually when that happens you skip dinner but today you had a very small lunch so you thought to yourself I might as well have some milk. So you went to the fridge to get some milk while you were drinking you read that 37% of the fat that was in the milk was removed leaving 5g of fat per glass. How many grams of fat are there in a glass of whole milk (milk in which none of the fat was removed)?

If 37% of the fat was removed, then 100% - 37% = 63% of the fat remained.
If x is the amount of fat in one glass of whole milk, then:
0.63x = 5
x = 7 . 9 3 6 5 = 8 (0 d. p.)
