27.5 is what percent of 82 - 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 82 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 82, so we can write it down as 100%=82.
4. We know, that x% equals 27.5 of the output value, so we can write it down as x%=27.5.
5. Now we have two simple equations:
1) 100%=82
2) x%=27.5
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%=82/27.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.5 is what percent of 82

100%/x%=82/27.5
(100/x)*x=(82/27.5)*x       - we multiply both sides of the equation by x
100=2.9818181818182*x       - we divide both sides of the equation by (2.9818181818182) to get x
100/2.9818181818182=x
33.536585365854=x
x=33.536585365854

now we have:
27.5 is 33.536585365854% of 82
