What is 0.09 percent of 220000 - 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 220000 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 220000 is 100%, so we can write it down as 220000=100%.
4. We know, that x is 0.09% of the output value, so we can write it down as x=0.09%.
5. Now we have two simple equations:
1) 220000=100%
2) x=0.09%
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:
220000/x=100%/0.09%
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 0.09% of 220000

220000/x=100/0.09
(220000/x)*x=(100/0.09)*x       - we multiply both sides of the equation by x
220000=1111.1111111111*x       - we divide both sides of the equation by (1111.1111111111) to get x
220000/1111.1111111111=x
198=x
x=198

now we have:
0.09% of 220000=198
