To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 319.85 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 319.85, so we can write it down as 100%=319.85.
4. We know, that x% equals 412.99 of the output value, so we can write it down as x%=412.99.
5. Now we have two simple equations:
1) 100%=319.85
2) x%=412.99
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%=319.85/412.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 412.99 is what percent of 319.85

(100/x)*x=(319.85/412.99)*x       - we multiply both sides of the equation by x
100=0.77447395820722*x       - we divide both sides of the equation by (0.77447395820722) to get x
100/0.77447395820722=x
129.1198999531=x
x=129.1198999531

now we have:
