480.4 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 480.4 of the output value, so we can write it down as x%=480.4.
5. Now we have two simple equations:
1) 100%=540
2) x%=480.4
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%=540/480.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 480.4 is what percent of 540

100%/x%=540/480.4
(100/x)*x=(540/480.4)*x       - we multiply both sides of the equation by x
100=1.1240632805995*x       - we divide both sides of the equation by (1.1240632805995) to get x
100/1.1240632805995=x
88.962962962963=x
x=88.962962962963

now we have:
480.4 is 88.962962962963% of 540
