220.8 is what percent of 200 - 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 200 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 200, so we can write it down as 100%=200.
4. We know, that x% equals 220.8 of the output value, so we can write it down as x%=220.8.
5. Now we have two simple equations:
1) 100%=200
2) x%=220.8
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%=200/220.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 220.8 is what percent of 200

100%/x%=200/220.8
(100/x)*x=(200/220.8)*x       - we multiply both sides of the equation by x
100=0.90579710144928*x       - we divide both sides of the equation by (0.90579710144928) to get x
100/0.90579710144928=x
110.4=x
x=110.4

now we have:
220.8 is 110.4% of 200
