Пошаговое объяснение:

1) 6. 1/7 - 5,75 =

6. 1/7 - 5. 75/100 =

6. 1/7 - 5. 3/4 =

6. 4/28 - 5. 21/28 =

5. 32/28 - 5. 21/28 = 11/28

2) 11/28 * (-1. 3/11) =

11/28 * (-14/11) = -14/28 = -1/2

3) 2,75 - 1. 5/6 =

2. 75/100 - 1. 5/6 =

2. 3/4 - 1. 5/6 =

2. 9/12 - 1. 10/12 =

1. 21/12 - 1. 10/12 = 11/12

4) 11/12 : 1/6 = 11/12 * 6/1 = 66/12 = 5. 6/12 = 5. 1/2

5) -1/2 + 5. 1/2 = 5
