(3 i 2/3 - 2 i 3/4) : 2 i 1/12 (3 i 8/12 - 2 i 9/12) : 2 i 1/2
---------------------------------------- = -------------------------------------- =
1 i 1/2 * 1 i 7/9 - 2/3 3/2 * 16/9 - 2/3
(2 i 20/12 - 2 i 9/12) : 2 i 1/12 11/12 : 25/12 11/12 * 12/25
--------------------------------------- = ---------------------- = ----------------------- =
3/2 * 16/9 - 2/3 8/3 - 2/3 6/3
11/25 : 6/3 = 11/25 * 3/6 = 33/150
