Answer 1

1i1/2+ 2i1/3 = 1i3/6 + 2i2/6 = 3i5/6

 

2i3/7 +2/5 = 2i 15/35 +14/35= 2i29/35

 

14i2/9 + 6i1/3= 14i2/9 + 6i3/9= 20i5/9

 

8i3/4 +1/6 +3i5/8= 8i18/24 +4/24 +3i15/24= 11i37/24= 12i13/24

 

2i8/11 -2/3= 2i24/33 - 22/33 = 2i2/33

 

16i5/8 - 2i1/3 = 16i15/24 - 2 i 8/24 = 14i7/24

 

2i3/8 -6/7 = 2i21/56 - 48/56= 1i77/56 - 48/56= 1i29/56

 

8i7/20 - 3i1/4= 8i7/20 -3i5/20 = 5i2/20= 5i1/10

 

6i2/9 -3 i8/8 = 6i2/9 - 4 = 2i2/9

 

13i7/12 - 9i8/9= 13i21/36 - 9i32/36 = 12i57/36 -9i32/36 = 3i25/36
