This sounds like first grade mathematics but I need to know the reasoning.
Why is it that to find a fraction of a number you multiply the number by that fraction?
ie to find (a/b)th of X you do X*(a/b). What operation is the multiplication doing in reality? This is used in precentages where you find a fraction of 100 by multiplying the fraction by 100.
