What is 8.6 percent of 12800 - 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 12800 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 12800 is 100%, so we can write it down as 12800=100%.
4. We know, that x is 8.6% of the output value, so we can write it down as x=8.6%.
5. Now we have two simple equations:
1) 12800=100%
2) x=8.6%
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:
12800/x=100%/8.6%
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 8.6% of 12800

12800/x=100/8.6
(12800/x)*x=(100/8.6)*x       - we multiply both sides of the equation by x
12800=11.627906976744*x       - we divide both sides of the equation by (11.627906976744) to get x
12800/11.627906976744=x
1100.8=x
x=1100.8

now we have:
8.6% of 12800=1100.8
