1. We assume, that the number 28641.4 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 28641.4, so we can write it down as 100%=28641.4.
4. We know, that x% equals 77.68 of the output value, so we can write it down as x%=77.68.
5. Now we have two simple equations:
1) 100%=28641.4
2) x%=77.68
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%=28641.4/77.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77.68 is what percent of 28641.4
