15.22 is what percent of 12 - step by step solution

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 100% equals 12, so we can write it down as 100%=12.
4. We know, that x% equals 15.22 of the output value, so we can write it down as x%=15.22.
5. Now we have two simple equations:
1) 100%=12
2) x%=15.22
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%=12/15.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.22 is what percent of 12

100%/x%=12/15.22
(100/x)*x=(12/15.22)*x       - we multiply both sides of the equation by x
100=0.78843626806833*x       - we divide both sides of the equation by (0.78843626806833) to get x
100/0.78843626806833=x
126.83333333333=x
x=126.83333333333

now we have:
15.22 is 126.83333333333% of 12
