6
6-1/2
7
7-1/2
none

Answer 1

To find out how many feet of fencing are left, we can subtract the length of the fencing that Jim used from the original length of the piece.

Original length of fencing = 9-1/2 feet
Length of fencing used = 2-1/2 feet

First, let's convert the mixed numbers into improper fractions:

- 9-1/2 feet = \( \frac{19}{2} \) feet
- 2-1/2 feet = \( \frac{5}{2} \) feet

Now, we can subtract the lengths:

\[
\frac{19}{2} - \frac{5}{2} = \frac{19 - 5}{2} = \frac{14}{2} = 7 \text{ feet}
\]

So, the amount of fencing left is **7 feet**.

Thus, the answer is **7**.
