What is 7.125 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 7.125% of the output value, so we can write it down as x=7.125%.
5. Now we have two simple equations:
1) 12=100%
2) x=7.125%
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%/7.125%
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 7.125% of 12

12/x=100/7.125
(12/x)*x=(100/7.125)*x       - we multiply both sides of the equation by x
12=14.035087719298*x       - we divide both sides of the equation by (14.035087719298) to get x
12/14.035087719298=x
0.855=x
x=0.855

now we have:
7.125% of 12=0.855
