1. We assume, that the number 2197.91 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 2197.91, so we can write it down as 100%=2197.91.
4. We know, that x% equals 394.84 of the output value, so we can write it down as x%=394.84.
5. Now we have two simple equations:
1) 100%=2197.91
2) x%=394.84
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%=2197.91/394.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 394.84 is what percent of 2197.91
