25 is what percent of 63.28 - 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 63.28 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 63.28, so we can write it down as 100%=63.28.
4. We know, that x% equals 25 of the output value, so we can write it down as x%=25.
5. Now we have two simple equations:
1) 100%=63.28
2) x%=25
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%=63.28/25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25 is what percent of 63.28

100%/x%=63.28/25
(100/x)*x=(63.28/25)*x       - we multiply both sides of the equation by x
100=2.5312*x       - we divide both sides of the equation by (2.5312) to get x
100/2.5312=x
39.506953223767=x
x=39.506953223767

now we have:
25 is 39.506953223767% of 63.28
