20 is what percent of 504.937 - 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 504.937 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 504.937, so we can write it down as 100%=504.937.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=504.937
2) x%=20
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%=504.937/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 504.937

100%/x%=504.937/20
(100/x)*x=(504.937/20)*x       - we multiply both sides of the equation by x
100=25.24685*x       - we divide both sides of the equation by (25.24685) to get x
100/25.24685=x
3.9608901704569=x
x=3.9608901704569

now we have:
20 is 3.9608901704569% of 504.937
