8 yd. 4 in. - 7 yd. 2 ft. 8 in.

Answer: 8 inches.

Step-by-step explanation: In order to solve this problem you need to subtract 7 yd. 2 ft. 8 in from 8 yd. 4 in.

First, change one yard in 8 yd. 4 in. to feet. So you will have 7 yds. 3 ft. 4 in.

Now the problem is 7 yd. 3 ft 4 in. - 7 yd. 2 ft. 8 in.

Subtracting the yards (7 - 7), there answer is 0.

The next step is to subtract the feet (3-2 = 1 ft)

You are left with 1 ft 4 in - 8 in

Lastly, you need to change 1 ft 4 inches to inches, 12 + 4 = 16 inches.

16 inches - 8 inches = 8 inches.
