Пошаговое объяснение:

1) 6. 1/8 - 1,75 = 6. 1/8 - 1. 75/1 00 =

6. 1/8 - 1. 3/4 = 6. 1/8 - 1. 6/8 =

5. 9/8 - 1. 6/8 = 4. 3/8

2) 5. 6/11 - 3,5 = 5. 6/11 - 3. 5/10 =

5. 6/11 - 3. 1/2 = 5. 12/22 - 3. 11/22 =

2. 1/22

3) 2,2 * 2. 1/22 = 2. 2/10 * 2. 1/22 =

2. 1/5 * 2. 1/22 = 11/5 * 45/22 =

1/1 * 9/2 = 9/2 = 4. 1/2

4) 9 - 4. 1/2 = 8. 2/2 - 4. 1/2 = 4. 1/2

5) 4. 3/8 : 4. 1/2 = 35/8 : 9/2 =

35/8 * 2/9 = 35/4 * 1/9 = 35/36

6) 35/36 * 1. 2/7 = 35/36 * 9/7 =

5/4 * 1/1 = 5/4 = 1. 1/4
