4. We know, that x% equals 969.56 of the output value, so we can write it down as x%=969.56.
5. Now we have two simple equations:
1) 100%=1221.95
2) x%=969.56
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%=1221.95/969.56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 969.56 is what percent of 1221.95
