9.9 is what percent of 110 - 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 110 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 110, so we can write it down as 100%=110.
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%=110
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%=110/9.9
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 110

100%/x%=110/9.9
(100/x)*x=(110/9.9)*x       - we multiply both sides of the equation by x
100=11.111111111111*x       - we divide both sides of the equation by (11.111111111111) to get x
100/11.111111111111=x
9=x
x=9

now we have:
9.9 is 9% of 110
