Пошаговое объяснение:

6)

а) 5 - 1 1/3 - 1 1/3 = 5 - 2 2/3 = 4 3/3 - 2 2/3 = 2 1/3;

б) 4 - (1 2/9 - 5/9) = 4 - (11/9 - 5/9) = 4 - 6/9 = 3 3/9 = 3 1/3;

в) 1 1/2 - 3/4 + 7/8 =

= 3/2 - 3/4 + 7/8 = 3/2*4/4 - 3/4*2/2 + 7/8 =

= 12/8 - 6/8 + 7/8 = 13/8 = 1 5/8;

г) 2 5/6 - 1 1/3 - 1/2 = 17/6 - 4/3 - 1/2 = 17/6 - 4/3*2/2 - 1/2*3/3 =

= 17/6 - 8/6 - 3/6 = 6/6 = 1.

Answer 2

Ответ:

Пошаговое объяснение:

а) 5 - 1. 1/3 - 1. 1/3 = 5 - (1. 1/3 - 1. 1/3) = 5 - 0 = 5

б) 4 - (1. 2/9 - 5/9) = 4 - (11/9 - 5/9) =

4 - 6/9 = 4 - 2/3 = 3. 3/3 - 2/3 = 3. 1/3

в) 1. 1/2 - 3/4 + 7/8 = 1. 4/8 - 6/8 + 7/8 = 12/8 - 6/8 + 7/8 = 13/8 = 1. 5/8

г) 2. 5/6 - 1. 1/3 - 1/2 = 2. 5/6 - 1. 2/6 - 3/6 = 1. 3/6 - 3/6 = 1
