8.2 is what percent of 15.1 - 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 15.1 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 15.1, so we can write it down as 100%=15.1.
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%=15.1
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%=15.1/8.2
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 15.1

100%/x%=15.1/8.2
(100/x)*x=(15.1/8.2)*x       - we multiply both sides of the equation by x
100=1.8414634146341*x       - we divide both sides of the equation by (1.8414634146341) to get x
100/1.8414634146341=x
54.304635761589=x
x=54.304635761589

now we have:
8.2 is 54.304635761589% of 15.1
