25 is what percent of 10216 - 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 10216 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 10216, so we can write it down as 100%=10216.
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%=10216
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%=10216/25
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 10216

100%/x%=10216/25
(100/x)*x=(10216/25)*x       - we multiply both sides of the equation by x
100=408.64*x       - we divide both sides of the equation by (408.64) to get x
100/408.64=x
0.24471417384495=x
x=0.24471417384495

now we have:
25 is 0.24471417384495% of 10216
