109.21 is what percent of 115.5 - 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 115.5 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 115.5, so we can write it down as 100%=115.5.
4. We know, that x% equals 109.21 of the output value, so we can write it down as x%=109.21.
5. Now we have two simple equations:
1) 100%=115.5
2) x%=109.21
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%=115.5/109.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 109.21 is what percent of 115.5

100%/x%=115.5/109.21
(100/x)*x=(115.5/109.21)*x       - we multiply both sides of the equation by x
100=1.0575954582914*x       - we divide both sides of the equation by (1.0575954582914) to get x
100/1.0575954582914=x
94.554112554113=x
x=94.554112554113

now we have:
109.21 is 94.554112554113% of 115.5
