130.15 is what percent of 507.5 - 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 507.5 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 507.5, so we can write it down as 100%=507.5.
4. We know, that x% equals 130.15 of the output value, so we can write it down as x%=130.15.
5. Now we have two simple equations:
1) 100%=507.5
2) x%=130.15
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%=507.5/130.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 130.15 is what percent of 507.5

100%/x%=507.5/130.15
(100/x)*x=(507.5/130.15)*x       - we multiply both sides of the equation by x
100=3.8993469074145*x       - we divide both sides of the equation by (3.8993469074145) to get x
100/3.8993469074145=x
25.645320197044=x
x=25.645320197044

now we have:
130.15 is 25.645320197044% of 507.5
