Odpowiedź:

9/10 : 3/8 = 9/10 * 8/3 = 3/5 * 4 = 12/5 = 2 i 2/5  

2/5 : 7/25 = 2/5 * 25/7 = 2 * 5/7 = 10/7 = 1 i 3/7  

5/9 : 35/6 = 5/9 * 6/35 = 1/3 * 2/7 = 2/21  

3 i 5/9 : 2 i 2/3 = 32/9 : 8/3 = 32/9 * 3/8 = 4/3 = 1 i 1/3  

1 i 1/4 : 4 i 1/6 = 5/4 : 25/6 = 5/4 * 6/25 = 3/10  

6 : 7 i 1/5 = 6 : 36/5 = 6 * 5/36 = 5/6
