If 37.54 is 100%, so we can write it down as 37.54=100%.
We know, that x is 12% of the output value, so we can write it down as x=12%.
Now we have two simple equations:
1) 37.54=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:
37.54/x=100%/12%
Now we just have to solve the simple equation, and we will get the solution we are looking for.
Solution for what is 12% of 37.54
37.54/x=100/12
(37.54/x)*x=(100/12)*x - we multiply both sides of the equation by x
37.54=8.3333333333333*x - we divide both sides of the equation by (8.3333333333333) to get x
37.54/8.3333333333333=x
4.5048=x
x=4.5048
now we have:
12% of 37.54=4.5048
