What is 8.13 percent of 15.5 - 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 15.5 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 15.5 is 100%, so we can write it down as 15.5=100%.
4. We know, that x is 8.13% of the output value, so we can write it down as x=8.13%.
5. Now we have two simple equations:
1) 15.5=100%
2) x=8.13%
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:
15.5/x=100%/8.13%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 8.13% of 15.5

15.5/x=100/8.13
(15.5/x)*x=(100/8.13)*x       - we multiply both sides of the equation by x
15.5=12.30012300123*x       - we divide both sides of the equation by (12.30012300123) to get x
15.5/12.30012300123=x
1.26015=x
x=1.26015

now we have:
8.13% of 15.5=1.26015
