Пошаговое объяснение:

1 1/4 * 2/5 - 1/3 = 5/4 * 2/5 - 1/3 = 10/20 - 1/3 =

1/2 - 1/3 = 3/6 - 2/6 = 1/6

5/6 : 1/3 + 1 3/8 = 5/6 * 3/1 + 1 3/8 = 15/6 + 1 3/8 =

5/2 + 1 3/8 = 20/8 + 1 3/8 = 2 4/8 + 1 3/8 = 3 7/8

2 1/3 : 1 5/9 - 5/6 = 7/3 : 14/9 - 5/6 =

7/3 * 9/14 - 5/6 = 1/1 * 3/2 - 5/6 = 3/2 - 5/6 =

9/6 - 5/6 = 4/6 = 2/3
