1. Answer:

   31/6 or 5 1/6( mixed fraction)

   Step-by-step explanation:

   the total length of 3 ropes would be

   2(5/6) + 1(1/7) + 3(1/3) ( mixed fraction )

   17/6 + 8/7 + 10/3

   (17(7) + 8(6) + 10(12))/42

   (119 + 48 + 120) / 42

   287/42

   41/6 ( divisible by 7 )

   so the length of 4th piece would be

   = 12 – 41/6

   = (72 – 41)/6

   = 31 / 6

   = 5 1/6 ( mixed fraction )
