What is 99.99 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 99.99% of the output value, so we can write it down as x=99.99%.
5. Now we have two simple equations:
1) 40000=100%
2) x=99.99%
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%/99.99%
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 99.99% of 40000

40000/x=100/99.99
(40000/x)*x=(100/99.99)*x       - we multiply both sides of the equation by x
40000=1.000100010001*x       - we divide both sides of the equation by (1.000100010001) to get x
40000/1.000100010001=x
39996=x
x=39996

now we have:
99.99% of 40000=39996
