Answer 1

3 i 7/9+6 i 2/3= 3 7/9 + 6 6/9 = 9 13/9 = 10 4/9
3/4+5/6+7/12= 9/12 + 10/12 + 7/12 = 26/12 = 2 2/12 = 2 1/6
4/15+1/6+7/5= 8/30 + 5/30 + 42/30 = 55/30 = 1 25/30 = 1 5/6
1 i 3/7+4/8+ 2 i 1/21= 1 72/168 + 84/162 + 2 8/168 = 3 164/168 = 3 41/42
7 i 7/36+ 95 i 5/8+ 4 i 5/6= 7 14/72 + 95 45/72 + 4 60/72 = 106 119/72 = 108 5/72
