1. Answer:

   39/29 days or 1.74 days

   Step-by-step explanation:

   A’s one day work = 1/2

   B’s one day work = 1/6

   C’s one day work = 1/13

   if all the three work together their one day work will be

   1/2 + 1/6 + 1/13

   => (39 + 13 + 6) / 78

   => 58/78

   => 29/39

   when we take the reciprocal, we will get the number of days required to complete the job if all the three work together

   => 39/29 => 1.74 days
