1. We assume, that the number 1581.07 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 1581.07, so we can write it down as 100%=1581.07.
4. We know, that x% equals 1269.11 of the output value, so we can write it down as x%=1269.11.
5. Now we have two simple equations:
1) 100%=1581.07
2) x%=1269.11
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%=1581.07/1269.11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1269.11 is what percent of 1581.07

(100/x)*x=(1581.07/1269.11)*x       - we multiply both sides of the equation by x
100=1.2458100558659*x       - we divide both sides of the equation by (1.2458100558659) to get x
100/1.2458100558659=x
80.269058295964=x
x=80.269058295964

now we have:
