What is 0.0005 percent of 500000 - 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 500000 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 500000 is 100%, so we can write it down as 500000=100%.
4. We know, that x is 0.0005% of the output value, so we can write it down as x=0.0005%.
5. Now we have two simple equations:
1) 500000=100%
2) x=0.0005%
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:
500000/x=100%/0.0005%
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 0.0005% of 500000

500000/x=100/0.0005
(500000/x)*x=(100/0.0005)*x       - we multiply both sides of the equation by x
500000=200000*x       - we divide both sides of the equation by (200000) to get x
500000/200000=x
2.5=x
x=2.5

now we have:
0.0005% of 500000=2.5
