What is 38.1 percent of 12.312 - 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 12.312 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 12.312 is 100%, so we can write it down as 12.312=100%.
4. We know, that x is 38.1% of the output value, so we can write it down as x=38.1%.
5. Now we have two simple equations:
1) 12.312=100%
2) x=38.1%
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:
12.312/x=100%/38.1%
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 38.1% of 12.312

12.312/x=100/38.1
(12.312/x)*x=(100/38.1)*x       - we multiply both sides of the equation by x
12.312=2.6246719160105*x       - we divide both sides of the equation by (2.6246719160105) to get x
12.312/2.6246719160105=x
4.690872=x
x=4.690872

now we have:
38.1% of 12.312=4.690872
