What is 69.69 percent of 12.39 - 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 12.39 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 12.39 is 100%, so we can write it down as 12.39=100%.
4. We know, that x is 69.69% of the output value, so we can write it down as x=69.69%.
5. Now we have two simple equations:
1) 12.39=100%
2) x=69.69%
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:
12.39/x=100%/69.69%
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 69.69% of 12.39

12.39/x=100/69.69
(12.39/x)*x=(100/69.69)*x       - we multiply both sides of the equation by x
12.39=1.4349261013058*x       - we divide both sides of the equation by (1.4349261013058) to get x
12.39/1.4349261013058=x
8.634591=x
x=8.634591

now we have:
69.69% of 12.39=8.634591
