Answer 1

A) 1/4 +1/8= 2/8+ 1/8= 3/8
    3/4 + 5/16= 6/16 + 5/16 = 11/16
     1/3 + 1/6 = 2/6+1/6= 3/6
b) 1/4 + 1/5 = 5/20 + 4/20 = 9/20
     3/10+ 2/25 = 15/50+ 4/50= 19/50
     1/5+ 1/25 = 5/25+ 1/25 = 6/25
c)  4/7+3/14 = 8/14 + 3/14 = 11/14
     1/3+1/7 = 7/21+ 3/21= 1-/21 
     7/8 + 8/9 = 63/72 + 68/71 = 131/72 = 1 59/72
d)  7/15+2/3 = 7/15 + 10/15 = 17/15 = 1 2/17
     1/8+1/9 = 9/72+8/72= 17/72
      5/6+7/8 = 40/48+42/48 = 82/48 = 1 34/40
