Answer: 10 11/12 feets
Explanation:
The tree has a height of 9 2/3 feet. We will be converting the mixed fraction to improper fraction, it becomes 29/3 feet's. So the tree has a height of 29/3 feets.
The tree grows an additional 1 1/4 feet. We would be converting it from mixed fraction to improper fraction. It becomes 5/4
To determine the new height of the tree, we would add the previous height + the growth in height of the tree. It becomes 29/3 + 5/4 = 131/12
We would convert from improper fraction to mixed fraction. It becomes
10 11/12 feets
