wait a minute. dont 10/100 automatically = 10%? Why are you multiplying by 100?
the formula is part over whole = X over 100
where X is expressed as percent.
So 10 over 100 equals X over 100
or isolating X to one side of the equation
10 times 100 over 100 = X
I explained this step by step but when I post it, it does not come out correctly. Sorry! I kinda wasted everyones time, but I hope you still understood.
