8 is what percent of 40.33 - 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 40.33 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 100% equals 40.33, so we can write it down as 100%=40.33.
4. We know, that x% equals 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=40.33
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:
100%/x%=40.33/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 40.33

100%/x%=40.33/8
(100/x)*x=(40.33/8)*x       - we multiply both sides of the equation by x
100=5.04125*x       - we divide both sides of the equation by (5.04125) to get x
100/5.04125=x
19.836350111579=x
x=19.836350111579

now we have:
8 is 19.836350111579% of 40.33
