506.3 is what percent of 655 - 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 655 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 655, so we can write it down as 100%=655.
4. We know, that x% equals 506.3 of the output value, so we can write it down as x%=506.3.
5. Now we have two simple equations:
1) 100%=655
2) x%=506.3
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%=655/506.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 506.3 is what percent of 655

100%/x%=655/506.3
(100/x)*x=(655/506.3)*x       - we multiply both sides of the equation by x
100=1.2936993877148*x       - we divide both sides of the equation by (1.2936993877148) to get x
100/1.2936993877148=x
77.297709923664=x
x=77.297709923664

now we have:
506.3 is 77.297709923664% of 655
