What is 9 percent of 2010 - 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 2010 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 2010 is 100%, so we can write it down as 2010=100%.
4. We know, that x is 9% of the output value, so we can write it down as x=9%.
5. Now we have two simple equations:
1) 2010=100%
2) x=9%
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:
2010/x=100%/9%
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 9% of 2010

2010/x=100/9
(2010/x)*x=(100/9)*x       - we multiply both sides of the equation by x
2010=11.111111111111*x       - we divide both sides of the equation by (11.111111111111) to get x
2010/11.111111111111=x
180.9=x
x=180.9

now we have:
9% of 2010=180.9
