1. i'm in a bit of a conundrum.
i'm trying to figure out how much thicker a surface is in percentages, so that i can multiply it with another number to figure out the % ratio. or something like that.

i have the number 436 and 580.

i wanted to find out which number to multiply 436 with to get 580.
so i figured, lets do it the old percentage way.

i did this:
580/100 = 5.8
436/5.8 = 75.1724
100-75.1724 = 24.8276

however, when i multiplied 436 by 1.248276, i get 544, not 580.
in order to get 580, i need to do this:

580/436 = 1.33028
then i multiply 436 by 1.33028.

so why is it that 436 is 75% of 580, but 580 is 133% bigger than 436?  2.

3. The simple answer is:
75% = 0.75 = 3/4
133.333...% = 1.33... = 4/3  Bookmarks
