82 is what percent of 2445 - 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 2445 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 2445, so we can write it down as 100%=2445.
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%=2445
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%=2445/82
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 2445

100%/x%=2445/82
(100/x)*x=(2445/82)*x       - we multiply both sides of the equation by x
100=29.817073170732*x       - we divide both sides of the equation by (29.817073170732) to get x
100/29.817073170732=x
3.3537832310838=x
x=3.3537832310838

now we have:
82 is 3.3537832310838% of 2445
