What is 0.005 percent of 8 - 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 8 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 8 is 100%, so we can write it down as 8=100%.
4. We know, that x is 0.005% of the output value, so we can write it down as x=0.005%.
5. Now we have two simple equations:
1) 8=100%
2) x=0.005%
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:
8/x=100%/0.005%
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 0.005% of 8

8/x=100/0.005
(8/x)*x=(100/0.005)*x       - we multiply both sides of the equation by x
8=20000*x       - we divide both sides of the equation by (20000) to get x
8/20000=x
0.0004=x
x=0.0004

now we have:
0.005% of 8=0.0004
