8 1/7 feet
8 5/12 feet
10 3/7 feet
10 11/12 feet

10 11/12 feets

Step-by-step 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
