It is! It looks like what you did here was to take 3/5 of 3 1/4, first by dividing by 5, and then by multiplying by 3. Just remember to leave your units (cups) on at the end! Also, you had a step there where you multiplied the improper fraction 3 1/4 = 13/4 by 5/5, so I’d show that step in your work.
