What is 12.4 percent of 17.1 - 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 17.1 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 17.1 is 100%, so we can write it down as 17.1=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) 17.1=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:
17.1/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 17.1

17.1/x=100/12.4
(17.1/x)*x=(100/12.4)*x       - we multiply both sides of the equation by x
17.1=8.0645161290323*x       - we divide both sides of the equation by (8.0645161290323) to get x
17.1/8.0645161290323=x
2.1204=x
x=2.1204

now we have:
12.4% of 17.1=2.1204
