Explanation:

First of all, per cent means per hundred or /100.
:. x% can be written as x/100.

Let 12 be x% of 200, where x can be any whole number(0 to infinity) or decimal number(numbers with a '.').

Then, 200 xx x% = 12
color(white)("XXX")200 xx x/100 = 12
Multiplying both sides by 100/200(in order to eliminate the numbers with x),
x = 12 xx 100/200 = 12 xx (1cancel(00))/(2cancel(00)) = 12/2 = 6
