What is 0.0004 percent of 15000000 - 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 15000000 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 15000000 is 100%, so we can write it down as 15000000=100%.
4. We know, that x is 0.0004% of the output value, so we can write it down as x=0.0004%.
5. Now we have two simple equations:
1) 15000000=100%
2) x=0.0004%
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:
15000000/x=100%/0.0004%
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 0.0004% of 15000000

15000000/x=100/0.0004
(15000000/x)*x=(100/0.0004)*x       - we multiply both sides of the equation by x
15000000=250000*x       - we divide both sides of the equation by (250000) to get x
15000000/250000=x
60=x
x=60

now we have:
0.0004% of 15000000=60
