109.5 is what percent of 307.5 - 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 307.5 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 307.5, so we can write it down as 100%=307.5.
4. We know, that x% equals 109.5 of the output value, so we can write it down as x%=109.5.
5. Now we have two simple equations:
1) 100%=307.5
2) x%=109.5
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%=307.5/109.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 109.5 is what percent of 307.5

100%/x%=307.5/109.5
(100/x)*x=(307.5/109.5)*x       - we multiply both sides of the equation by x
100=2.8082191780822*x       - we divide both sides of the equation by (2.8082191780822) to get x
100/2.8082191780822=x
35.609756097561=x
x=35.609756097561

now we have:
109.5 is 35.609756097561% of 307.5
