Пошаговое объяснение:

А) 1. 1/2 + 3 = (1+3) + 1/2 = 4 + 1/2 = 4. 1/2

Б) 5. 3/4 + 2. 1/4 = (5+2) + (3+1)/4 =

7 + 4/4 = 7 + 1 = 8

В) 7. 2/5 - 3. 4/5 = 6. 7/5 - 3. 4/5 =

(6-3) + (7-4)/5 = 3 + 3/5 = 3. 3/5

Г) 8. 1/6 - 3. 3/6 = 7. 7/6 - 3. 3/6 =

(7-3) + (7-3)/6 = 4 + 4/6 = 4. 4/6 = 4. 2/3

Д) 9 - 1/6 = 8. 6/6 - 1/6 = 8 + (6-1)/6 =

8 + 5/6 = 8. 5/6

Е) 10 - 3/7 = 9. 7/7 - 3/7 = 9 + (7-3)/7 = 9 + 4/7 = 9. 4/7

Ж) 10. 1/3 - 1/2 = 10. 2/6 - 3/6 = 9. 8/6 - 3/6 = 9 + (8-3)/6 = 9 + 5/6 = 9. 5/6

З) 11. 1/5 - 2/5 = 10. 6/5 - 2/5 = 10 + (6-2)/5 = 10 + 4/5 = 10. 4/5
