312.38 is what percent of 506 - 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 506 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 506, so we can write it down as 100%=506.
4. We know, that x% equals 312.38 of the output value, so we can write it down as x%=312.38.
5. Now we have two simple equations:
1) 100%=506
2) x%=312.38
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%=506/312.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 312.38 is what percent of 506

100%/x%=506/312.38
(100/x)*x=(506/312.38)*x       - we multiply both sides of the equation by x
100=1.6198220116525*x       - we divide both sides of the equation by (1.6198220116525) to get x
100/1.6198220116525=x
61.735177865613=x
x=61.735177865613

now we have:
312.38 is 61.735177865613% of 506
