What is 0.0001 percent of 0.2 - 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 0.2 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 0.2 is 100%, so we can write it down as 0.2=100%.
4. We know, that x is 0.0001% of the output value, so we can write it down as x=0.0001%.
5. Now we have two simple equations:
1) 0.2=100%
2) x=0.0001%
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:
0.2/x=100%/0.0001%
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 0.0001% of 0.2

0.2/x=100/0.0001
(0.2/x)*x=(100/0.0001)*x       - we multiply both sides of the equation by x
0.2=1000000*x       - we divide both sides of the equation by (1000000) to get x
0.2/1000000=x
2.0E-7=x
x=2.0E-7

now we have:
0.0001% of 0.2=2.0E-7
