507.5 is what percent of 15660 - 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 15660 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 15660, so we can write it down as 100%=15660.
4. We know, that x% equals 507.5 of the output value, so we can write it down as x%=507.5.
5. Now we have two simple equations:
1) 100%=15660
2) x%=507.5
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%=15660/507.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 507.5 is what percent of 15660

100%/x%=15660/507.5
(100/x)*x=(15660/507.5)*x       - we multiply both sides of the equation by x
100=30.857142857143*x       - we divide both sides of the equation by (30.857142857143) to get x
100/30.857142857143=x
3.2407407407407=x
x=3.2407407407407

now we have:
507.5 is 3.2407407407407% of 15660
