The easy way to do percents is to always use the proportion:
%/100 = part/whole
or
%/100 = "is"/"of"
So, in this problem you will plug in for % and "is":
90/100 = 324/x
Cross multiply and you get: 90x = 32400
Divide both sides by 90: x = 360
So 324 is 90% of 360.
I hope this helps!

90% *x = 324
(90/100)x = 324
90x = 324 * 100
90x = 32400
9x = 3240
x = 3240/9
x = 360

here is an easy way to solve these problems, find what ten percent is....
90% is 324 so you can divide 324 by nine, you get 36.....36 is ten percent of the whole number so multiply it by ten
36 * 10 = 360

Let x be the number.
90 % of x is 324.
324=90x/100
multiply both sides by 100
90x=32400
9x=3240
x=360

REMEMBER:
Is........%
---- = ------
of 100
so:
324......90
------ = ------ You can reduce, 90 and 100 w/ a 10 so ur left w/:
x.......... 100
324....... 9
------- = ------- You can reduce, 9 and 324 w/ a 3 so ur left w/:
x...........10
18......3
----- = ------ Reduce the 3 and the 18 with a 3 so ur left w/ :
x..........10
6..........1
----- = ------- Cross multiply 6 and 10 so ur left w/ x=60
x ........10
