Re: Percentage of a Number ?You have the number and you want to reduce it by 45%. First you calculate what 45% of the number is and then you would subtract it from the number. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
