Body fat percentage can be found using the following formula.

100 x Amount of body fat/total body weight = % body fat which would be

100 x X/200=25%

They ask to find the amount of body fat.

I came up with this formula

25/100 x 200 = X

So X would be 50 lbs for the amount of body fat

then they ask how much weight he would lose if he was down to 18% body fat

18/100 x 200 = X

so that would be 36 lbs

Am i completely off? or do i have this correct?
