What is 12 percent of 316.88 - 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 316.88 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 316.88 is 100%, so we can write it down as 316.88=100%.
4. We know, that x is 12% of the output value, so we can write it down as x=12%.
5. Now we have two simple equations:
1) 316.88=100%
2) x=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:
316.88/x=100%/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 12% of 316.88

316.88/x=100/12
(316.88/x)*x=(100/12)*x       - we multiply both sides of the equation by x
316.88=8.3333333333333*x       - we divide both sides of the equation by (8.3333333333333) to get x
316.88/8.3333333333333=x
38.0256=x
x=38.0256

now we have:
12% of 316.88=38.0256
