8.2 is what percent of 130 - 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 130 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 130, so we can write it down as 100%=130.
4. We know, that x% equals 8.2 of the output value, so we can write it down as x%=8.2.
5. Now we have two simple equations:
1) 100%=130
2) x%=8.2
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%=130/8.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.2 is what percent of 130

100%/x%=130/8.2
(100/x)*x=(130/8.2)*x       - we multiply both sides of the equation by x
100=15.853658536585*x       - we divide both sides of the equation by (15.853658536585) to get x
100/15.853658536585=x
6.3076923076923=x
x=6.3076923076923

now we have:
8.2 is 6.3076923076923% of 130
