1) 14/75 и 8/15 = 14/75 < 40/75

2) 9/16 и 4/9 = 81/144 > 64/144

3) 5/12 и 3/8 = 10/24 > 9/24

4) 7/32 и 13/24 = 21/96 < 52/96

5) 8/105 и 7/135 = 72/945 > 49/945

6) 13/25, 11/15 и 3/20 = 156/300,? 220/300 и 45/300-вот тут я не поняла, что надо?

7) 5/2 а и 8/3 а = 15/6 а < 16/6 а

8) b/8 сd и n/10d = 5b/40cd > 4cn/40cd
