8 is what percent of 220000 - 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 220000 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 220000, so we can write it down as 100%=220000.
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%=220000
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%=220000/8
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 220000

100%/x%=220000/8
(100/x)*x=(220000/8)*x       - we multiply both sides of the equation by x
100=27500*x       - we divide both sides of the equation by (27500) to get x
100/27500=x
0.0036363636363636=x
x=0.0036363636363636

now we have:
8 is 0.0036363636363636% of 220000
