[AI-generated answer — Bot GPT 3.5]

To find the amount of fencing left, you need to subtract the amount of fencing used from the total length of the piece.

The total length of the piece is 9-1/2 feet.
The amount of fencing used is 2-1/2 feet.

So, the amount of fencing left is 9-1/2 feet - 2-1/2 feet.

To subtract mixed numbers, you need to find a common denominator. The common denominator of 2 and 1 is 2.

Converting 9-1/2 to a fraction with a denominator of 2:
9-1/2 = 18/2 - 1/2 = 17/2.

Converting 2-1/2 to a fraction with a denominator of 2:
2-1/2 = 4/2 - 1/2 = 3/2.

So, the amount of fencing left is 17/2 - 3/2 = (17-3)/2 = 14/2 = 7.

Therefore, there are 7 feet of fencing left.
