Umm can you explain to me exactlly how to that

Well, we would rather weigh more in kilograms than we would in pounds. So the number of kilograms is smaller than the number of pounds.

Unfortunately, we cannot do your homework for you, we can only guide you.

There are 2.205 pounds per kilogram. So, how many kilograms does a 150 pound man weigh?
Alternatively, 1 pound = 0.4536 kilograms.
