Пошаговое объяснение:

№1

1) 2. 1/3 - 2/5 = 2. 5/15 - 6/15 = 1. 20/15 - 6/15 = 1. 14/15

2) 1. 14/15 + 0,5 = 1. 14/15 + 5/10 = 1. 28/30 + 15/30 = 1. 43/30 = 2. 13/30

3) 2. 13/30 + 2. 3/5 = 2. 13/30 + 2. 18/30 = 4. 31/30 = 5. 1/30

№2

1) 1,2 - 3/5 = 1. 2/10 - 3/5 = 1. 1/5 - 3/5 = 6/5 - 3/5 = 3/5

2) 3/5 + 2. 1/2 = 6/10 + 2. 5/10 = 2. 11/10 = 3. 1/10

3) 3. 1/10 + 3. 2/5 = 3. 1/10 + 3. 4/10 = 6. 5/10 = 6. 1/2
