What is 3.25 percent of 39990 - 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 39990 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 39990 is 100%, so we can write it down as 39990=100%.
4. We know, that x is 3.25% of the output value, so we can write it down as x=3.25%.
5. Now we have two simple equations:
1) 39990=100%
2) x=3.25%
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:
39990/x=100%/3.25%
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 3.25% of 39990

39990/x=100/3.25
(39990/x)*x=(100/3.25)*x       - we multiply both sides of the equation by x
39990=30.769230769231*x       - we divide both sides of the equation by (30.769230769231) to get x
39990/30.769230769231=x
1299.675=x
x=1299.675

now we have:
3.25% of 39990=1299.675
