9.1 is what percent of 8.3 - 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 8.3 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 8.3, so we can write it down as 100%=8.3.
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%=8.3
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%=8.3/9.1
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 8.3

100%/x%=8.3/9.1
(100/x)*x=(8.3/9.1)*x       - we multiply both sides of the equation by x
100=0.91208791208791*x       - we divide both sides of the equation by (0.91208791208791) to get x
100/0.91208791208791=x
109.63855421687=x
x=109.63855421687

now we have:
9.1 is 109.63855421687% of 8.3
