1. We assume, that the number 26785.05 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 26785.05, so we can write it down as 100%=26785.05.
4. We know, that x% equals 640.04 of the output value, so we can write it down as x%=640.04.
5. Now we have two simple equations:
1) 100%=26785.05
2) x%=640.04
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%=26785.05/640.04
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 640.04 is what percent of 26785.05

(100/x)*x=(26785.05/640.04)*x       - we multiply both sides of the equation by x
100=41.849025060934*x       - we divide both sides of the equation by (41.849025060934) to get x
100/41.849025060934=x
2.3895419273065=x
x=2.3895419273065

now we have:
