What is 0.0007 percent of 400500 - 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 400500 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 400500 is 100%, so we can write it down as 400500=100%.
4. We know, that x is 0.0007% of the output value, so we can write it down as x=0.0007%.
5. Now we have two simple equations:
1) 400500=100%
2) x=0.0007%
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:
400500/x=100%/0.0007%
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 0.0007% of 400500

400500/x=100/0.0007
(400500/x)*x=(100/0.0007)*x       - we multiply both sides of the equation by x
400500=142857.14285714*x       - we divide both sides of the equation by (142857.14285714) to get x
400500/142857.14285714=x
2.8035=x
x=2.8035

now we have:
0.0007% of 400500=2.8035
