A mechanical engineer designs a robotic rm to be used in an assembly line. one portion of the arm is 5/12 yard long, and the length of the second portion of the arm is 3/12 yard long. What wouldbe the length, in yards, of the robotic arm if the two portions of the arm were measured end to end?

  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.
