Take an example if you had 10 strawberries and you ate 2 then you have consumed 20 percent of strawberries out of all and left with 80 percent of the things. The word per cent means per 100. That means you are at the 80th percentile.
Cell C2 contains the number 20 equal to the 02 value.
Lets explore the three basic percentage problems. N number of values in the data set P Percentile. P is 10 X is 150 so the equation is 10 150 Y. You can think of the most basic as XY P x 100.
