9.1 is what percent of 38 - 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 38 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 38, so we can write it down as 100%=38.
4. We know, that x% equals 9.1 of the output value, so we can write it down as x%=9.1.
5. Now we have two simple equations:
1) 100%=38
2) x%=9.1
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%=38/9.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.1 is what percent of 38

100%/x%=38/9.1
(100/x)*x=(38/9.1)*x       - we multiply both sides of the equation by x
100=4.1758241758242*x       - we divide both sides of the equation by (4.1758241758242) to get x
100/4.1758241758242=x
23.947368421053=x
x=23.947368421053

now we have:
9.1 is 23.947368421053% of 38
