What is 0.04 percent of 40000 - 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 40000 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 40000 is 100%, so we can write it down as 40000=100%.
4. We know, that x is 0.04% of the output value, so we can write it down as x=0.04%.
5. Now we have two simple equations:
1) 40000=100%
2) x=0.04%
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:
40000/x=100%/0.04%
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 0.04% of 40000

40000/x=100/0.04
(40000/x)*x=(100/0.04)*x       - we multiply both sides of the equation by x
40000=2500*x       - we divide both sides of the equation by (2500) to get x
40000/2500=x
16=x
x=16

now we have:
0.04% of 40000=16
