What is 99 percent of 9000 - 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 9000 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 9000 is 100%, so we can write it down as 9000=100%.
4. We know, that x is 99% of the output value, so we can write it down as x=99%.
5. Now we have two simple equations:
1) 9000=100%
2) x=99%
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:
9000/x=100%/99%
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 99% of 9000

9000/x=100/99
(9000/x)*x=(100/99)*x       - we multiply both sides of the equation by x
9000=1.010101010101*x       - we divide both sides of the equation by (1.010101010101) to get x
9000/1.010101010101=x
8910=x
x=8910

now we have:
99% of 9000=8910
