1. 7/8 + 5/2 = 7/8 + 20/8 = 27/8

   3/7 + 5/2 = 6/14 + 35/14 = 41/14

   12/13-5/13 = 7/13

   5-5/15 = 45/15 – 5/15 = 40/15 = 8/3

   9/4-2 = 9/4 – 8/4 = 1/4

   11/12 + 3/4 = 11/12 + 9/12 = 20/12 = 5/3

   5/6 + 3 = 5/6 + 18/6 = 23/6 

   8/5 – 4/7 = 56/35 – 20/35 = 36/35

   9/4 – 2 = 9/4 – 8/4 = 1/4
