What is 0.00015 percent of 100000 - 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 100000 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 100000 is 100%, so we can write it down as 100000=100%.
4. We know, that x is 0.00015% of the output value, so we can write it down as x=0.00015%.
5. Now we have two simple equations:
1) 100000=100%
2) x=0.00015%
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:
100000/x=100%/0.00015%
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 0.00015% of 100000

100000/x=100/0.00015
(100000/x)*x=(100/0.00015)*x       - we multiply both sides of the equation by x
100000=666666.66666667*x       - we divide both sides of the equation by (666666.66666667) to get x
100000/666666.66666667=x
0.15=x
x=0.15

now we have:
0.00015% of 100000=0.15
