72.5 is what percent of 82.39 - 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 82.39 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 82.39, so we can write it down as 100%=82.39.
4. We know, that x% equals 72.5 of the output value, so we can write it down as x%=72.5.
5. Now we have two simple equations:
1) 100%=82.39
2) x%=72.5
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%=82.39/72.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72.5 is what percent of 82.39

100%/x%=82.39/72.5
(100/x)*x=(82.39/72.5)*x       - we multiply both sides of the equation by x
100=1.1364137931034*x       - we divide both sides of the equation by (1.1364137931034) to get x
100/1.1364137931034=x
87.996116033499=x
x=87.996116033499

now we have:
72.5 is 87.996116033499% of 82.39
