39 is what percent of 114 - 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 114 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 114, so we can write it down as 100%=114.
4. We know, that x% equals 39 of the output value, so we can write it down as x%=39.
5. Now we have two simple equations:
1) 100%=114
2) x%=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%=114/39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39 is what percent of 114

100%/x%=114/39
(100/x)*x=(114/39)*x       - we multiply both sides of the equation by x
100=2.92307692308*x       - we divide both sides of the equation by (2.92307692308) to get x
100/2.92307692308=x
34.2105263158=x
x=34.2105263158

now we have:
39 is 34.2105263158% of 114
