What is 2009 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 200 is 100%, so we can write it down as 200=100%.
4. We know, that x is 2009% of the output value, so we can write it down as x=2009%.
5. Now we have two simple equations:
1) 200=100%
2) x=2009%
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:
200/x=100%/2009%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2009% of 200

200/x=100/2009
(200/x)*x=(100/2009)*x       - we multiply both sides of the equation by x
200=0.049776007964161*x       - we divide both sides of the equation by (0.049776007964161) to get x
200/0.049776007964161=x
4018=x
x=4018

now we have:
2009% of 200=4018
