What is 28.6 percent of 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 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 39 is 100%, so we can write it down as 39=100%.
4. We know, that x is 28.6% of the output value, so we can write it down as x=28.6%.
5. Now we have two simple equations:
1) 39=100%
2) x=28.6%
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:
39/x=100%/28.6%
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 28.6% of 39

39/x=100/28.6
(39/x)*x=(100/28.6)*x       - we multiply both sides of the equation by x
39=3.4965034965035*x       - we divide both sides of the equation by (3.4965034965035) to get x
39/3.4965034965035=x
11.154=x
x=11.154

now we have:
28.6% of 39=11.154
