What is 0.001 percent of 503000000 - 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 503000000 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 503000000 is 100%, so we can write it down as 503000000=100%.
4. We know, that x is 0.001% of the output value, so we can write it down as x=0.001%.
5. Now we have two simple equations:
1) 503000000=100%
2) x=0.001%
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:
503000000/x=100%/0.001%
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 0.001% of 503000000

503000000/x=100/0.001
(503000000/x)*x=(100/0.001)*x       - we multiply both sides of the equation by x
503000000=100000*x       - we divide both sides of the equation by (100000) to get x
503000000/100000=x
5030=x
x=5030

now we have:
0.001% of 503000000=5030
