12.5 is what percent of 459.5 - 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 459.5 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 459.5, so we can write it down as 100%=459.5.
4. We know, that x% equals 12.5 of the output value, so we can write it down as x%=12.5.
5. Now we have two simple equations:
1) 100%=459.5
2) x%=12.5
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%=459.5/12.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.5 is what percent of 459.5

100%/x%=459.5/12.5
(100/x)*x=(459.5/12.5)*x       - we multiply both sides of the equation by x
100=36.76*x       - we divide both sides of the equation by (36.76) to get x
100/36.76=x
2.7203482045702=x
x=2.7203482045702

now we have:
12.5 is 2.7203482045702% of 459.5
