8 is what percent of 1800000 - 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 1800000 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 100% equals 1800000, so we can write it down as 100%=1800000.
4. We know, that x% equals 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=1800000
2) x%=8
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:
100%/x%=1800000/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 1800000

100%/x%=1800000/8
(100/x)*x=(1800000/8)*x       - we multiply both sides of the equation by x
100=225000*x       - we divide both sides of the equation by (225000) to get x
100/225000=x
0.00044444444444444=x
x=0.00044444444444444

now we have:
8 is 0.00044444444444444% of 1800000
