510.5 is what percent of 565 - 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 565 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 565, so we can write it down as 100%=565.
4. We know, that x% equals 510.5 of the output value, so we can write it down as x%=510.5.
5. Now we have two simple equations:
1) 100%=565
2) x%=510.5
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%=565/510.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 510.5 is what percent of 565

100%/x%=565/510.5
(100/x)*x=(565/510.5)*x       - we multiply both sides of the equation by x
100=1.1067580803134*x       - we divide both sides of the equation by (1.1067580803134) to get x
100/1.1067580803134=x
90.353982300885=x
x=90.353982300885

now we have:
510.5 is 90.353982300885% of 565
