Question

A man who weighs 200 lbs goes on a diet and loses 16%of his body weight. How much weight, in ounces, did he loses?

Answer 1

We know that the man loses 16% of his weight, to find how much was that we just have to multiply his total weight by 0.16, like this:

lost weight = 0.16 * total weight, by replacing 200 lbs for total weight, we get:

lost weight = 0.16 * 200 = 32

Now we need to express 32 lbs in ounces, we can do this by multiplying the weight in pounds by 16, since 1 pound is equivalent to 16 ounces, then we get:

lost weight in ounces = 32 * 16 = 512

Then, the man lost 512 ounces
