Answer: The answer is 3 3/5 because you divide 2 1/4 and 5/8 you do KCF keep change flip but since it is a whole number divided by a fraction you multiply the whole number with the denominator and than add it by the numerator so no the problem is 9/4 • 8/5 which is 72/20 which is a improper fraction so it is 3 12/20 but it can be reduced to 3 3/5 and thats how you do it.
