Answer:

1 1/4 inches

5/48 foot

Explanation:

to solve this question, convert feet to inches

1 feet = 12 inches

8 x 12 = 96 inches

7feet,10 3/4 inches long = (7 x 12) + 10 3/4 inches = 94 3/4 inches

Subtract 94 3/4 inches from 96 inches

96 inches - 94 3/4 inches = 1 1/4 inches

or 5/4 x 1/12 = 5/48 foot
