What is 3.75 percent of 310.8 - 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 310.8 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 310.8 is 100%, so we can write it down as 310.8=100%.
4. We know, that x is 3.75% of the output value, so we can write it down as x=3.75%.
5. Now we have two simple equations:
1) 310.8=100%
2) x=3.75%
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:
310.8/x=100%/3.75%
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 3.75% of 310.8

310.8/x=100/3.75
(310.8/x)*x=(100/3.75)*x       - we multiply both sides of the equation by x
310.8=26.666666666667*x       - we divide both sides of the equation by (26.666666666667) to get x
310.8/26.666666666667=x
11.655=x
x=11.655

now we have:
3.75% of 310.8=11.655
