103.5 is what percent of 115.9 - 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 115.9 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 115.9, so we can write it down as 100%=115.9.
4. We know, that x% equals 103.5 of the output value, so we can write it down as x%=103.5.
5. Now we have two simple equations:
1) 100%=115.9
2) x%=103.5
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%=115.9/103.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 103.5 is what percent of 115.9

100%/x%=115.9/103.5
(100/x)*x=(115.9/103.5)*x       - we multiply both sides of the equation by x
100=1.119806763285*x       - we divide both sides of the equation by (1.119806763285) to get x
100/1.119806763285=x
89.301121656601=x
x=89.301121656601

now we have:
103.5 is 89.301121656601% of 115.9
