311.1 is what percent of 2800 - step by step solution

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

1. We assume, that the number 2800 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 2800, so we can write it down as 100%=2800.
4. We know, that x% equals 311.1 of the output value, so we can write it down as x%=311.1.
5. Now we have two simple equations:
1) 100%=2800
2) x%=311.1
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%=2800/311.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 311.1 is what percent of 2800

100%/x%=2800/311.1
(100/x)*x=(2800/311.1)*x       - we multiply both sides of the equation by x
100=9.0003214400514*x       - we divide both sides of the equation by (9.0003214400514) to get x
100/9.0003214400514=x
11.110714285714=x
x=11.110714285714

now we have:
311.1 is 11.110714285714% of 2800
