25 is what percent of 656 - 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 656 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 656, so we can write it down as 100%=656.
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%=656
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%=656/25
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 656

100%/x%=656/25
(100/x)*x=(656/25)*x       - we multiply both sides of the equation by x
100=26.24*x       - we divide both sides of the equation by (26.24) to get x
100/26.24=x
3.8109756097561=x
x=3.8109756097561

now we have:
25 is 3.8109756097561% of 656
