Odpowiedź:
2 i 2/3 : 6/7 = 8/3 : 6/7 = 8/3 * 7/6 = 28/9 = 3 i 1/9
4 i 1/3 : 3/5 = 13/3 : 3/5 = 13/3 * 5/3 = 65/9 = 7 i 2/9
3 i 3/4 : 2/3 = 15/4 : 2/3 = 15/4 * 3/2 = 45/8 = 5 i 5/8
1 i 1/2 : 1 i 2/3 = 3/2 : 5/3 = 3/2 * 3/5 = 9/10
4/5 : 1 i 1/6 = 4/5 : 7/6 = 4/5 * 6/7 = 24/35
9/20 : 2 i 5/7 = 9/29 : 19/7 = 9/29 * 7/19 = 63/380
