0.39 is what percent of 13.27 - 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 13.27 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 13.27, so we can write it down as 100%=13.27.
4. We know, that x% equals 0.39 of the output value, so we can write it down as x%=0.39.
5. Now we have two simple equations:
1) 100%=13.27
2) x%=0.39
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%=13.27/0.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.39 is what percent of 13.27

100%/x%=13.27/0.39
(100/x)*x=(13.27/0.39)*x       - we multiply both sides of the equation by x
100=34.025641025641*x       - we divide both sides of the equation by (34.025641025641) to get x
100/34.025641025641=x
2.9389600602864=x
x=2.9389600602864

now we have:
0.39 is 2.9389600602864% of 13.27
