12.5 is what percent of 480 - 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 480 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 480, so we can write it down as 100%=480.
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%=480
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%=480/12.5
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 480

100%/x%=480/12.5
(100/x)*x=(480/12.5)*x       - we multiply both sides of the equation by x
100=38.4*x       - we divide both sides of the equation by (38.4) to get x
100/38.4=x
2.6041666666667=x
x=2.6041666666667

now we have:
12.5 is 2.6041666666667% of 480
