To me, it makes me think that I am supposed to multiply it by 1 (because 100% is equal to 1, like .9 is equal to 90%). I know you multiply it by 100, but I was just confused why the percent sign was there? Also, what is the actual math problem to find out the number of objects in a container?

For instance, they can test what drugs are in a persons system, or figure out what type of substances are in a certain object, and much more. I always wonder how they figured out how to do that.
