What is 0.325 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 0.325% of the output value, so we can write it down as x=0.325%.
5. Now we have two simple equations:
1) 39=100%
2) x=0.325%
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%/0.325%
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 0.325% of 39

39/x=100/0.325
(39/x)*x=(100/0.325)*x       - we multiply both sides of the equation by x
39=307.69230769231*x       - we divide both sides of the equation by (307.69230769231) to get x
39/307.69230769231=x
0.12675=x
x=0.12675

now we have:
0.325% of 39=0.12675
