If an athlete weighs 147 lb and has 15.0 % body fat by weight, how many pounds of fat does the athlete's body contain?

I think I answered a question just like this the other day. To get the weight of the body fat, multiply the total body weight by the percentage of the body fat (as a decimal, which would be 0.15).
So, you would do this:
147x0.15=22.05
The athlete's body contains 22.05 pounds of fat.

Your welcome xD .......
