All servings add up to 6 3/4 cups (convert to 27/4 cups). Each serving (I believe the problem indicates) is 1 1/2 cups (convert to 3/2). So to get the number of servings, divide the total by the amount of each serving:
27/4 divided by 3/2. (remember, to divide fractions, invert the 2nd fraction and multiply the 2).
27/4 x 2/3 = 54/12 = 9/2, or 4 1/2 servings.
