What is 31.37 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 31.37% of the output value, so we can write it down as x=31.37%.
5. Now we have two simple equations:
1) 12=100%
2) x=31.37%
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%/31.37%
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 31.37% of 12

12/x=100/31.37
(12/x)*x=(100/31.37)*x       - we multiply both sides of the equation by x
12=3.1877590054192*x       - we divide both sides of the equation by (3.1877590054192) to get x
12/3.1877590054192=x
3.7644=x
x=3.7644

now we have:
31.37% of 12=3.7644
