25.45 is what percent of 39.36 - 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 39.36 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 39.36, so we can write it down as 100%=39.36.
4. We know, that x% equals 25.45 of the output value, so we can write it down as x%=25.45.
5. Now we have two simple equations:
1) 100%=39.36
2) x%=25.45
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%=39.36/25.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.45 is what percent of 39.36

100%/x%=39.36/25.45
(100/x)*x=(39.36/25.45)*x       - we multiply both sides of the equation by x
100=1.5465618860511*x       - we divide both sides of the equation by (1.5465618860511) to get x
100/1.5465618860511=x
64.659552845528=x
x=64.659552845528

now we have:
25.45 is 64.659552845528% of 39.36
