82 is what percent of 609 - 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 609 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 609, so we can write it down as 100%=609.
4. We know, that x% equals 82 of the output value, so we can write it down as x%=82.
5. Now we have two simple equations:
1) 100%=609
2) x%=82
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%=609/82
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 82 is what percent of 609

100%/x%=609/82
(100/x)*x=(609/82)*x       - we multiply both sides of the equation by x
100=7.4268292682927*x       - we divide both sides of the equation by (7.4268292682927) to get x
100/7.4268292682927=x
13.464696223317=x
x=13.464696223317

now we have:
82 is 13.464696223317% of 609
