1. We assume, that the number 4.75 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 4.75 is 100%, so we can write it down as 4.75=100%.
4. We know, that x is 8% of the output value, so we can write it down as x=8%.
5. Now we have two simple equations:
1) 4.75=100%
2) x=8%
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:
4.75/x=100%/8%
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 8% of 4.75
4.75/x=100/8
(4.75/x)*x=(100/8)*x - we multiply both sides of the equation by x
4.75=12.5*x - we divide both sides of the equation by (12.5) to get x
4.75/12.5=x
0.38=x
x=0.38
now we have:
8% of 4.75=0.38
