8.91 is what percent of 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 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 33, so we can write it down as 100%=33.
4. We know, that x% equals 8.91 of the output value, so we can write it down as x%=8.91.
5. Now we have two simple equations:
1) 100%=33
2) x%=8.91
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%=33/8.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.91 is what percent of 33

100%/x%=33/8.91
(100/x)*x=(33/8.91)*x       - we multiply both sides of the equation by x
100=3.7037037037037*x       - we divide both sides of the equation by (3.7037037037037) to get x
100/3.7037037037037=x
27=x
x=27

now we have:
8.91 is 27% of 33
