521.16 is what percent of 10300 - 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 10300 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 10300, so we can write it down as 100%=10300.
4. We know, that x% equals 521.16 of the output value, so we can write it down as x%=521.16.
5. Now we have two simple equations:
1) 100%=10300
2) x%=521.16
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%=10300/521.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 521.16 is what percent of 10300

100%/x%=10300/521.16
(100/x)*x=(10300/521.16)*x       - we multiply both sides of the equation by x
100=19.763604267403*x       - we divide both sides of the equation by (19.763604267403) to get x
100/19.763604267403=x
5.0598058252427=x
x=5.0598058252427

now we have:
521.16 is 5.0598058252427% of 10300
