What is 57.2 percent of 12 - 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 12 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 12 is 100%, so we can write it down as 12=100%.
4. We know, that x is 57.2% of the output value, so we can write it down as x=57.2%.
5. Now we have two simple equations:
1) 12=100%
2) x=57.2%
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:
12/x=100%/57.2%
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 57.2% of 12

12/x=100/57.2
(12/x)*x=(100/57.2)*x       - we multiply both sides of the equation by x
12=1.7482517482517*x       - we divide both sides of the equation by (1.7482517482517) to get x
12/1.7482517482517=x
6.864=x
x=6.864

now we have:
57.2% of 12=6.864
