25 is what percent of 697.6 - 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 697.6 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 697.6, so we can write it down as 100%=697.6.
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%=697.6
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%=697.6/25
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 697.6

100%/x%=697.6/25
(100/x)*x=(697.6/25)*x       - we multiply both sides of the equation by x
100=27.904*x       - we divide both sides of the equation by (27.904) to get x
100/27.904=x
3.5837155963303=x
x=3.5837155963303

now we have:
25 is 3.5837155963303% of 697.6
