1. We assume, that the number 7734.21 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 7734.21, so we can write it down as 100%=7734.21.
4. We know, that x% equals 990.23 of the output value, so we can write it down as x%=990.23.
5. Now we have two simple equations:
1) 100%=7734.21
2) x%=990.23
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%=7734.21/990.23
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 990.23 is what percent of 7734.21
