Пошаговое объяснение:

1) 3. 1/3 + 5. 1/6 = 3. 2/6 + 5. 1/6 = 8. 3/6 = 8. 1/2

2) 8. 1/2 * 2/5 = 17/2 * 2/5 = 17/5 = 3. 2/5

3) 1. 1/2 - 2/5 = 1. 5/10 - 4/10 = 1. 1/10

4) 2. 3/4 : 1. 1/10 = 11/4 : 11/10 = 11/4 * 10/11 = 10/4 = 2. 2/4 = 2. 1/2

5) 3. 2/5 - 2. 1/2 = 3. 4/10 - 2. 5/10 = 2. 14/10 - 2. 5/10 = 9/10

1) 3. 1/3 * 2. 2/5 = 10/3 * 12/5 = 2/1 * 4/1 = 8/1 = 8

2) 4. 8/15 * 3/17 = 68/15 * 3/17 = 4/5 * 1/1 = 4/5

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

4) 8 + 1. 1/5 = 9. 1/5

1) 1/8 + 2/9 - 1/4 = 9/72 + 16/72 - 18/72 =

7/72

2) 7/9 - 2/3 + 1/6 = 14/18 - 12/18 + 3/18 =

5/18

3) 7/72 * 5. 1/7 = 7/72 * 36/7 = 36/72 = 1/2

4) 1/2 : 5/18 = 1/2 * 18/5 = 1/1 * 9/5 = 9/5 =

1. 4/5

1) 12 : 1. 1/5 = 12 : 6/5 = 12 * 5/6 = 60/6 = 10

2) 10. 3/4 - 10 = 3/4

3) 3/4 * 4/9 = 3/9 = 1/3

4) 3. 1/4 : 5. 1/5 = 13/4 : 26/5 = 13/4 * 5/26 = 1/4 * 5/2 = 5/8

5) 1/3 + 2. 1/6 + 5/8 = 8/24 + 2. 4/24 + 15/24 = 2. 27/24 = 3. 3/24 = 3. 1/8
