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

1. We assume, that the number 307.99 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 307.99, so we can write it down as 100%=307.99.
4. We know, that x% equals 289.79 of the output value, so we can write it down as x%=289.79.
5. Now we have two simple equations:
1) 100%=307.99
2) x%=289.79
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%=307.99/289.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 289.79 is what percent of 307.99

(100/x)*x=(307.99/289.79)*x       - we multiply both sides of the equation by x
100=1.0628040995203*x       - we divide both sides of the equation by (1.0628040995203) to get x
100/1.0628040995203=x
94.090717231079=x
x=94.090717231079

now we have:
