39.15 is what percent of 56 - 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 56 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 56, so we can write it down as 100%=56.
4. We know, that x% equals 39.15 of the output value, so we can write it down as x%=39.15.
5. Now we have two simple equations:
1) 100%=56
2) x%=39.15
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%=56/39.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.15 is what percent of 56

100%/x%=56/39.15
(100/x)*x=(56/39.15)*x       - we multiply both sides of the equation by x
100=1.4303959131545*x       - we divide both sides of the equation by (1.4303959131545) to get x
100/1.4303959131545=x
69.910714285714=x
x=69.910714285714

now we have:
39.15 is 69.910714285714% of 56
