What is 4.5 percent of 408000 - 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 408000 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 408000 is 100%, so we can write it down as 408000=100%.
4. We know, that x is 4.5% of the output value, so we can write it down as x=4.5%.
5. Now we have two simple equations:
1) 408000=100%
2) x=4.5%
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:
408000/x=100%/4.5%
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 4.5% of 408000

408000/x=100/4.5
(408000/x)*x=(100/4.5)*x       - we multiply both sides of the equation by x
408000=22.222222222222*x       - we divide both sides of the equation by (22.222222222222) to get x
408000/22.222222222222=x
18360=x
x=18360

now we have:
4.5% of 408000=18360
