What is 7.12 percent of 391.68 - 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 391.68 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 391.68 is 100%, so we can write it down as 391.68=100%.
4. We know, that x is 7.12% of the output value, so we can write it down as x=7.12%.
5. Now we have two simple equations:
1) 391.68=100%
2) x=7.12%
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:
391.68/x=100%/7.12%
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 7.12% of 391.68

391.68/x=100/7.12
(391.68/x)*x=(100/7.12)*x       - we multiply both sides of the equation by x
391.68=14.044943820225*x       - we divide both sides of the equation by (14.044943820225) to get x
391.68/14.044943820225=x
27.887616=x
x=27.887616

now we have:
7.12% of 391.68=27.887616
