What is 12.31 percent of 80.55 - 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 80.55 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 80.55 is 100%, so we can write it down as 80.55=100%.
4. We know, that x is 12.31% of the output value, so we can write it down as x=12.31%.
5. Now we have two simple equations:
1) 80.55=100%
2) x=12.31%
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:
80.55/x=100%/12.31%
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 12.31% of 80.55

80.55/x=100/12.31
(80.55/x)*x=(100/12.31)*x       - we multiply both sides of the equation by x
80.55=8.123476848091*x       - we divide both sides of the equation by (8.123476848091) to get x
80.55/8.123476848091=x
9.915705=x
x=9.915705

now we have:
12.31% of 80.55=9.915705
