Answer:

30.6%, see explanation for what you're asking for

Explanation:

Set up a proportion equation. You know 108 is 100%, so keeping the percents on the top, 100%/108 = x%/33. There's no "nice" number multipliers here, but you can still divide 100 by 108, take that number, and multiply it by 33 to get x. This is because you're finding how to get from 108 to 100 (bottom to top) to see that proportion, then applying it to the bottom number under x, the top, which you want. Doing this gives me 0.936 (approx.), and multiplying this by 33 gives me 30.555 repeating, which can be rounded up to 30.6%.

I can't figure out why you're getting a number like 32.67%. Perhaps it's a rounding error? I hope this helps despite it being a week after your asking.
