(x / 120) * 100 = y 100/120= 0.8333 0.8333 * 100 = 83.333 (answer) Test - (83.333 / 100) * 120 = 100

I've made a note of that so I don't need to remember it. But I can't remember where I put the note...

| Say I need to know what number 100 is 20% more than, like so: x + 20% = 100 |
|
100-20% = x That was easy...

It is not important to know everything, but it is important to know where to look for the answer, as well as how to find the answer. Once one figures out the routine it is fairly easy to apply that formula to pretty much every situation one is faced with... Thus pointers in(to) memory are faster than inline evaluation.

I may not have known the right answer, but I knew that was wrong! ;) 20% of 80 is 16, meaning 96, not 100, is 20% more than 80. See briggidere's test case...

to see what 100 is 20% more than 100 / 1.20 ( of course this is the same as 100/1.2 but i use 1.20 to be clear.
