Answer 1

2i5/7+1i5/6=4 i 23/42

1i4/5+2i5/6=4 i 19/30

Answer 2

2i5/7 +1i5/6= 2i30/42 + 1i35/42 = 3i65/42 = 4i23/42

 

1i4/5 +2i5/6= 1i24/30 + 2i25/30 = 3i49/30 = 4i19/30

 

5i3/4 - 2i1/7 = 5i21/28 - 2i4/28 = 3i17/28

 

6i2/9 -4i3/8= 6i16/72 - 4i27/72 =5i88/72 -4i27/72 = 1i61/72

 

4i3/7 -3i1/6= 4i18/42 - 3i7/42 = 1i11/42

 

7i4/9 -5i5/8= 7i32/72 - 5i45/72= 6i104/72 -5i45/72= 1i59/72

 

7/13 * 9/14 = 1/13 * 9/2 = 9/26 

 

4/5 : 16/35 = 4/5 * 35/16 = 1/1 * 7/4 = 7/4 = 1i3/4

 

2i1/5 * 7i1/2 = 11/5 * 15/2 = 11/1 * 3/2 = 33/2 = 16 i 1/2
