Пошаговое объяснение:

1) 3/20 + 2/15 = 6/60 + 8/60 = 14/60 = 7/30

2) 17/32 - 5/12 = 51/96 - 40/96 = 11/96

3) 11/28 + 9/14 = 11/28 + 18/28 = 29/28 = 1. 1/28

4) 35/36 - 41/45 = 175/180 - 164/180 = 11/180

5) 3. 21/25 + 1. 2/5 =

3. 21/25 + 1. 10/25 =

4. 31/25 = 5. 6/25

6) 4. 13/16 - 2. 3/8 =

4. 13/16 - 2. 6/16 = 2. 7/16

7) 5. 5/6 - 31/48 =

5. 40/48 - 31/48 =

5. 9/48 = 5. 3/16

8) 6. 4/7 - 2. 37/77 =

6. 44/77 - 2. 37/77 =

4. 7/77 =4. 1/11
