36 is 12 percent of what number?

Answers

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 100% equals 12, so we can write it down as 100%=12.
4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.
5. Now we have two simple equations:
1) 100%=12
2) x%=36
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:
100%/x%=12/36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36 is what percent of 12

100%/x%=12/36
(100/x)*x=(12/36)*x - we multiply both sides of the equation by x
100=0.333333333333*x - we divide both sides of the equation by (0.333333333333) to get x
100/0.333333333333=x
300=x
x=300

now we have:
36 is 300% of 12
