What is 450000 percent of 18 - 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 18 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 18 is 100%, so we can write it down as 18=100%.
4. We know, that x is 450000% of the output value, so we can write it down as x=450000%.
5. Now we have two simple equations:
1) 18=100%
2) x=450000%
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:
18/x=100%/450000%
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 450000% of 18

18/x=100/450000
(18/x)*x=(100/450000)*x       - we multiply both sides of the equation by x
18=0.00022222222222222*x       - we divide both sides of the equation by (0.00022222222222222) to get x
18/0.00022222222222222=x
81000=x
x=81000

now we have:
450000% of 18=81000
