42800 is what percent of 9 - 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 9 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 9, so we can write it down as 100%=9.
4. We know, that x% equals 42800 of the output value, so we can write it down as x%=42800.
5. Now we have two simple equations:
1) 100%=9
2) x%=42800
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%=9/42800
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42800 is what percent of 9

100%/x%=9/42800
(100/x)*x=(9/42800)*x       - we multiply both sides of the equation by x
100=0.00021028037383178*x       - we divide both sides of the equation by (0.00021028037383178) to get x
100/0.00021028037383178=x
475555.55555556=x
x=475555.55555556

now we have:
42800 is 475555.55555556% of 9
