8/12 yard or 2/3 yard

Step-by-step explanation:

The sum of the two lengths is ...

5/12 yd + 3/12 yd = (5+3) / 12 yd = 8/12 yd

This fraction can be reduced by removing a factor of 4 from numerator and denominator.

8/12 yd = 2/3 yd

If the arm portions are end-to-end, the total length is 2/3 yard.
