515.5 is what percent of 540 - 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 540 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 540, so we can write it down as 100%=540.
4. We know, that x% equals 515.5 of the output value, so we can write it down as x%=515.5.
5. Now we have two simple equations:
1) 100%=540
2) x%=515.5
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%=540/515.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 515.5 is what percent of 540

100%/x%=540/515.5
(100/x)*x=(540/515.5)*x       - we multiply both sides of the equation by x
100=1.0475266731329*x       - we divide both sides of the equation by (1.0475266731329) to get x
100/1.0475266731329=x
95.462962962963=x
x=95.462962962963

now we have:
515.5 is 95.462962962963% of 540
