40 is what percent of 1116 - 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 1116 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 1116, so we can write it down as 100%=1116.
4. We know, that x% equals 40 of the output value, so we can write it down as x%=40.
5. Now we have two simple equations:
1) 100%=1116
2) x%=40
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%=1116/40
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40 is what percent of 1116

100%/x%=1116/40
(100/x)*x=(1116/40)*x       - we multiply both sides of the equation by x
100=27.9*x       - we divide both sides of the equation by (27.9) to get x
100/27.9=x
3.584229390681=x
x=3.584229390681

now we have:
40 is 3.584229390681% of 1116
