To add mixed numbers, we first add the whole numbers together. In this case, the whole numbers are 16, 15, 15, 16, and 16, which add up to 78. Next, we add the fractions together. The fractions 3/14, 2/3, 3/7, 17/14, and 2/3 have different denominators, so we need to find a common denominator. The least common multiple of 14, 3, and 7 is 42. Converting the fractions to have a denominator of 42, we get 9/42, 28/42, 18/42, 51/42, and 28/42. Adding these fractions together gives us 134/42. Simplifying this fraction, we get 67/21. Therefore, the final answer is 78 67/21, which can be written as 16 3/14.
