81.55 is what percent of 75.5 - 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 75.5 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 75.5, so we can write it down as 100%=75.5.
4. We know, that x% equals 81.55 of the output value, so we can write it down as x%=81.55.
5. Now we have two simple equations:
1) 100%=75.5
2) x%=81.55
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%=75.5/81.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.55 is what percent of 75.5

100%/x%=75.5/81.55
(100/x)*x=(75.5/81.55)*x       - we multiply both sides of the equation by x
100=0.92581238503985*x       - we divide both sides of the equation by (0.92581238503985) to get x
100/0.92581238503985=x
108.01324503311=x
x=108.01324503311

now we have:
81.55 is 108.01324503311% of 75.5
