509.59 is what percent of 570 - 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 570 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 570, so we can write it down as 100%=570.
4. We know, that x% equals 509.59 of the output value, so we can write it down as x%=509.59.
5. Now we have two simple equations:
1) 100%=570
2) x%=509.59
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%=570/509.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 509.59 is what percent of 570

100%/x%=570/509.59
(100/x)*x=(570/509.59)*x       - we multiply both sides of the equation by x
100=1.1185462823054*x       - we divide both sides of the equation by (1.1185462823054) to get x
100/1.1185462823054=x
89.401754385965=x
x=89.401754385965

now we have:
509.59 is 89.401754385965% of 570
