8517.6 is what percent of 13520 - 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 13520 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 13520, so we can write it down as 100%=13520.
4. We know, that x% equals 8517.6 of the output value, so we can write it down as x%=8517.6.
5. Now we have two simple equations:
1) 100%=13520
2) x%=8517.6
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%=13520/8517.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8517.6 is what percent of 13520

100%/x%=13520/8517.6
(100/x)*x=(13520/8517.6)*x       - we multiply both sides of the equation by x
100=1.5873015873016*x       - we divide both sides of the equation by (1.5873015873016) to get x
100/1.5873015873016=x
63=x
x=63

now we have:
8517.6 is 63% of 13520
