What is 0.018 percent of 0.02 - 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 0.02 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 0.02 is 100%, so we can write it down as 0.02=100%.
4. We know, that x is 0.018% of the output value, so we can write it down as x=0.018%.
5. Now we have two simple equations:
1) 0.02=100%
2) x=0.018%
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:
0.02/x=100%/0.018%
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 0.018% of 0.02

0.02/x=100/0.018
(0.02/x)*x=(100/0.018)*x       - we multiply both sides of the equation by x
0.02=5555.5555555556*x       - we divide both sides of the equation by (5555.5555555556) to get x
0.02/5555.5555555556=x
3.6E-6=x
x=3.6E-6

now we have:
0.018% of 0.02=3.6E-6
