Пошаговое объяснение:

3) 1 7/12 : (3/8 + 5/12) = 1 7/12 : (9/24 + 10/24) = 1 7/12 : 19/24 = 19/12 : 19/24 = 19/12 * 24/19 = 2/1 = 2

==========================

4) 17/36 : (7/12 - 5/9) = 17/36 : (21/36 - 20/36) = 17/36 : 1/36 = 17/36 * 36/1 = 17/1 = 17

==========================

5) (3/14 + 5/7) : 3 5/7 = (3/14 + 10/14) : 3 5/7 = 13/14 : 3 5/7 = 13/14 : 26/7 = 13/14 * 7/26 = 1/4 = 0,25

==========================

6) 19/24 : (3/16 + 5/24) = 19/24 : (9/48 + 10/48) = 19/24 : 19/48 = 19/24 * 48/19 = 2/1 = 2
