39.07 is what percent of 70 - 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 70 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 70, so we can write it down as 100%=70.
4. We know, that x% equals 39.07 of the output value, so we can write it down as x%=39.07.
5. Now we have two simple equations:
1) 100%=70
2) x%=39.07
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%=70/39.07
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.07 is what percent of 70

100%/x%=70/39.07
(100/x)*x=(70/39.07)*x       - we multiply both sides of the equation by x
100=1.7916560020476*x       - we divide both sides of the equation by (1.7916560020476) to get x
100/1.7916560020476=x
55.814285714286=x
x=55.814285714286

now we have:
39.07 is 55.814285714286% of 70
