We express the percentage as follows:
111% = 111 out of 100 = 111/100
then we write an equation for the problem statement:
(111%)(x) = 33.3
that is to say that a number x multiplied by the 111% is equal to 33.3, so we solve for x:
(111/100)(x) = 33.3
111x = (33.3)(100) = 3330
x = 3330/111
x = 30
therefore the number is 30, and we can say that 111% of 30 equals to 33.3
