What is 12.66 percent of 69 - 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 69 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 69 is 100%, so we can write it down as 69=100%.
4. We know, that x is 12.66% of the output value, so we can write it down as x=12.66%.
5. Now we have two simple equations:
1) 69=100%
2) x=12.66%
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:
69/x=100%/12.66%
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 12.66% of 69

69/x=100/12.66
(69/x)*x=(100/12.66)*x       - we multiply both sides of the equation by x
69=7.8988941548183*x       - we divide both sides of the equation by (7.8988941548183) to get x
69/7.8988941548183=x
8.7354=x
x=8.7354

now we have:
12.66% of 69=8.7354
