What is 0.0015 percent of 15000 - 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 15000 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 15000 is 100%, so we can write it down as 15000=100%.
4. We know, that x is 0.0015% of the output value, so we can write it down as x=0.0015%.
5. Now we have two simple equations:
1) 15000=100%
2) x=0.0015%
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:
15000/x=100%/0.0015%
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 0.0015% of 15000

15000/x=100/0.0015
(15000/x)*x=(100/0.0015)*x       - we multiply both sides of the equation by x
15000=66666.666666667*x       - we divide both sides of the equation by (66666.666666667) to get x
15000/66666.666666667=x
0.225=x
x=0.225

now we have:
0.0015% of 15000=0.225
