What is 12.4 percent of 325 - 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 325 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 325 is 100%, so we can write it down as 325=100%.
4. We know, that x is 12.4% of the output value, so we can write it down as x=12.4%.
5. Now we have two simple equations:
1) 325=100%
2) x=12.4%
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:
325/x=100%/12.4%
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 12.4% of 325

325/x=100/12.4
(325/x)*x=(100/12.4)*x       - we multiply both sides of the equation by x
325=8.0645161290323*x       - we divide both sides of the equation by (8.0645161290323) to get x
325/8.0645161290323=x
40.3=x
x=40.3

now we have:
12.4% of 325=40.3
