Пошаговое объяснение:

3/8 и 15/16 => (3*2)/(8*2) и 15/16 => 6/16 и 15/16

5/9 и 41/81 => (5*9)/(9*9) и 41/81 => 45/81 и 41/81

5/14 и 23/70 => (5*5)/(14*5) и 23/70 => 25/70 и 23/70

9/100 и 7/25 => 9/100 и (7*4)/(25*4) => 9/100 и 28/100

11/75 и 14/15 => 11/75 и (14*5)/(15*5) => 11/75 и 70/75

19/80 и 13/16 => 19/80 и (13*5)/(16*5) => 19/80 и 65/80
