3.89 is what percent of 33.5 - 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 33.5 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 33.5, so we can write it down as 100%=33.5.
4. We know, that x% equals 3.89 of the output value, so we can write it down as x%=3.89.
5. Now we have two simple equations:
1) 100%=33.5
2) x%=3.89
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%=33.5/3.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.89 is what percent of 33.5

100%/x%=33.5/3.89
(100/x)*x=(33.5/3.89)*x       - we multiply both sides of the equation by x
100=8.6118251928021*x       - we divide both sides of the equation by (8.6118251928021) to get x
100/8.6118251928021=x
11.611940298507=x
x=11.611940298507

now we have:
3.89 is 11.611940298507% of 33.5
