11.5 is what percent of 9.15 - 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 9.15 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 9.15, so we can write it down as 100%=9.15.
4. We know, that x% equals 11.5 of the output value, so we can write it down as x%=11.5.
5. Now we have two simple equations:
1) 100%=9.15
2) x%=11.5
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%=9.15/11.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.5 is what percent of 9.15

100%/x%=9.15/11.5
(100/x)*x=(9.15/11.5)*x       - we multiply both sides of the equation by x
100=0.79565217391304*x       - we divide both sides of the equation by (0.79565217391304) to get x
100/0.79565217391304=x
125.68306010929=x
x=125.68306010929

now we have:
11.5 is 125.68306010929% of 9.15
