Answer:
13 feet
Step-by-step explanation:
1 yard = 3 feet
4 yards = 12 feet
1/3 yard = 1 foot
12 feet + 1 foot = 13 feet
We can drop the absolute value and the signs, and the integer part if they're all the same, and then make a common denominator and check for a decreasing sequence.
10/12, 7/12, 5/12 -- Check decreasing
3 1/3, 3 2/3, 2 2/3 -- nope, increases then decreases
6 5/7, 6 3/7, 5 2/7 - Check, decreasing
11 7/10, 11 6/10, 10 3/10 -- Check, decreasing
