What is 9000 percent of 210000 - 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 210000 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 210000 is 100%, so we can write it down as 210000=100%.
4. We know, that x is 9000% of the output value, so we can write it down as x=9000%.
5. Now we have two simple equations:
1) 210000=100%
2) x=9000%
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:
210000/x=100%/9000%
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 9000% of 210000

210000/x=100/9000
(210000/x)*x=(100/9000)*x       - we multiply both sides of the equation by x
210000=0.011111111111111*x       - we divide both sides of the equation by (0.011111111111111) to get x
210000/0.011111111111111=x
18900000=x
x=18900000

now we have:
9000% of 210000=18900000
