What is 0.405 percent of 2000 - 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 2000 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 2000 is 100%, so we can write it down as 2000=100%.
4. We know, that x is 0.405% of the output value, so we can write it down as x=0.405%.
5. Now we have two simple equations:
1) 2000=100%
2) x=0.405%
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:
2000/x=100%/0.405%
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 0.405% of 2000

2000/x=100/0.405
(2000/x)*x=(100/0.405)*x       - we multiply both sides of the equation by x
2000=246.91358024691*x       - we divide both sides of the equation by (246.91358024691) to get x
2000/246.91358024691=x
8.1=x
x=8.1

now we have:
0.405% of 2000=8.1
