What is 43.6 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 43.6% of the output value, so we can write it down as x=43.6%.
5. Now we have two simple equations:
1) 39=100%
2) x=43.6%
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%/43.6%
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 43.6% of 39

39/x=100/43.6
(39/x)*x=(100/43.6)*x       - we multiply both sides of the equation by x
39=2.2935779816514*x       - we divide both sides of the equation by (2.2935779816514) to get x
39/2.2935779816514=x
17.004=x
x=17.004

now we have:
43.6% of 39=17.004
