how do I find the percentage of 18/20

or for this and any other problem . every percentage is out of a 100 soooo , 20 | 100 %10 | 50 %5 | 25 %1 | 5 %SOOO 10 + 5 = 15 50 % + 25 % = 75 % , so know we know 15/20 is 75 percentbut you need 18/20 not 15/20 , so 1 equals 5 % in this problem 1+1+1 = 3 5+5+5 = 1515 + 3 = 90 75 + 15 = 90 , 18/20 = 90%I know its probably alot but I wanted to show you all I did , so that it could maybe help you in the future , just gotta plug in different numbers

U divide them together and u get 0.9 and that as a percent is 90%
