3.66 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 3.66 of the output value, so we can write it down as x%=3.66.
5. Now we have two simple equations:
1) 100%=9.15
2) x%=3.66
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%=9.15/3.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.66 is what percent of 9.15

100%/x%=9.15/3.66
(100/x)*x=(9.15/3.66)*x       - we multiply both sides of the equation by x
100=2.5*x       - we divide both sides of the equation by (2.5) to get x
100/2.5=x
40=x
x=40

now we have:
3.66 is 40% of 9.15
