What is 0.002 percent of 19500000 - 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 19500000 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 19500000 is 100%, so we can write it down as 19500000=100%.
4. We know, that x is 0.002% of the output value, so we can write it down as x=0.002%.
5. Now we have two simple equations:
1) 19500000=100%
2) x=0.002%
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:
19500000/x=100%/0.002%
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 0.002% of 19500000

19500000/x=100/0.002
(19500000/x)*x=(100/0.002)*x       - we multiply both sides of the equation by x
19500000=50000*x       - we divide both sides of the equation by (50000) to get x
19500000/50000=x
390=x
x=390

now we have:
0.002% of 19500000=390
