9.9 is what percent of 28000 - 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 28000 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 28000, so we can write it down as 100%=28000.
4. We know, that x% equals 9.9 of the output value, so we can write it down as x%=9.9.
5. Now we have two simple equations:
1) 100%=28000
2) x%=9.9
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%=28000/9.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.9 is what percent of 28000

100%/x%=28000/9.9
(100/x)*x=(28000/9.9)*x       - we multiply both sides of the equation by x
100=2828.2828282828*x       - we divide both sides of the equation by (2828.2828282828) to get x
100/2828.2828282828=x
0.035357142857143=x
x=0.035357142857143

now we have:
9.9 is 0.035357142857143% of 28000
