(3 i 3/5 + 2 i 4/5) : 6/7 = 5 i 7/5 : 6/7 = 32/5 * 7/6 = 224/30 = 7 i 14/30

3/4 : 4 i 1/2 + 7 : 1 i 1/9 = 3/4 : 9/2 + 7 : 10/9 = 3/4 * 2/9 + 7 * 9/10 = 1/6 + 63/10 = 10/60 + 378/60 = 388/60 = 6 i 28/60

3/5 : (1 i 1/2 - 3/4) = 3/5 : (1 i 2/4 - 3/4) = 3/5 : (6/4 - 3/4) = 3/5 : 3/4 = 3/5 * 4/3 = 4/5
