To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 12 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 12 is 100%, so we can write it down as 12=100%.
4. We know, that x is 81.81% of the output value, so we can write it down as x=81.81%.
5. Now we have two simple equations:
1) 12=100%
2) x=81.81%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
12/x=100%/81.81%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 81.81% of 12

12/x=100/81.81

12=1.2223444566679*x       - we divide both sides of the equation by (1.2223444566679) to get x
12/1.2223444566679=x
9.8172=x
x=9.8172

now we have:
81.81% of 12=9.8172
