To find the height of the tree after six months, we need to add the growth of 2 3/4 inches to the original height of 74 3/8 inches.
Adding the fractions:
3/8 + 3/8 = 6/8 = 3/4
Adding the whole numbers:
74 + 2 = 76
So, the height of the tree after six months is 76 3/4 inches.
The closest answer choice is B. 76 1/2 inches. However, since 76 1/2 inches is smaller than 76 3/4 inches, we need to round up to the closest whole number.
Thus, the height of the tree is 77 inches.
Therefore, the correct answer is D. 77 1/2 inches.
