58.75 is what percent of 81.5 - 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 81.5 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 81.5, so we can write it down as 100%=81.5.
4. We know, that x% equals 58.75 of the output value, so we can write it down as x%=58.75.
5. Now we have two simple equations:
1) 100%=81.5
2) x%=58.75
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%=81.5/58.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 58.75 is what percent of 81.5

100%/x%=81.5/58.75
(100/x)*x=(81.5/58.75)*x       - we multiply both sides of the equation by x
100=1.3872340425532*x       - we divide both sides of the equation by (1.3872340425532) to get x
100/1.3872340425532=x
72.085889570552=x
x=72.085889570552

now we have:
58.75 is 72.085889570552% of 81.5
