Answer:
Araceli would have used 2.25 (or 2 1/4) yards of fabric for each bag. 
Step-by-step explanation:
First, you have the 9 bags you are making and they all must be the same because they are identical, so you divide the nine bags by the four yards and I got an answer of 2.25 yards per bag. The answer can also be 2 1/4 as well.
