What is 0.00081 percent of 100 - 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 100 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 100 is 100%, so we can write it down as 100=100%.
4. We know, that x is 0.00081% of the output value, so we can write it down as x=0.00081%.
5. Now we have two simple equations:
1) 100=100%
2) x=0.00081%
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:
100/x=100%/0.00081%
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 0.00081% of 100

100/x=100/0.00081
(100/x)*x=(100/0.00081)*x       - we multiply both sides of the equation by x
100=123456.79012346*x       - we divide both sides of the equation by (123456.79012346) to get x
100/123456.79012346=x
0.00081=x
x=0.00081

now we have:
0.00081% of 100=0.00081
