9.9 is what percent of 94.2 - 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 94.2 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 94.2, so we can write it down as 100%=94.2.
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%=94.2
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%=94.2/9.9
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 94.2

100%/x%=94.2/9.9
(100/x)*x=(94.2/9.9)*x       - we multiply both sides of the equation by x
100=9.5151515151515*x       - we divide both sides of the equation by (9.5151515151515) to get x
100/9.5151515151515=x
10.509554140127=x
x=10.509554140127

now we have:
9.9 is 10.509554140127% of 94.2
