What are your choices?
Both Brady and I showed you how to simplify that fraction.

What goes into both 90 and 20?
5, right?
Well, just divide them each by 5 to get it even more simplified.
90/5 = 18
20/5 = 4
Now you have 18/4.
What goes into both 18 and 4?
2, right?
Now divide each by 2.
18/2 = 9
4/2 = 2
Now you have 9/2.
Now, you turn it into a mixed fraction, by figuring out how many 2's go into 9.
Four 2's go into 9 with a 1 left over.
Now you have 4 1/2, which is your final answer. I hope this helps! :)

Damon is correct as well. His way is a lot easier for fractions when both the numerator and denominator have zeros after their first digits.
