To add the fractions, we need to have a common denominator.
The common denominator of 8 and 4 is 8.
Converting 3 & 3/8 to an improper fraction, we get 27/8.
Converting 2 & 1/4 to an improper fraction, we get 9/4.
Adding the two fractions, we get 27/8 + 9/4.
Multiplying 27/8 by 1/1, we get 27/8.
Multiplying 9/4 by 2/2, we get 18/8.
Adding the fractions, we have 27/8 + 18/8 = 45/8.
Since we cannot have a fraction in terms of cups, we convert the fraction to a mixed number.
Dividing the numerator 45 by the denominator 8, we get 5 with a remainder of 5.
The mixed number equivalent of 45/8 is 5 5/8.
