Пошаговое объяснение:

А) = -11/5 + 3. 1/3 - 7/5 + 3. 2/3 + 2. 1/5 =

(-11/5 - 7/5 + 2. 1/5) + (3. 1/3 + 3. 2/3) =

(-18/5 + 2. 1/5) + 6. 3/3 =

(-3. 3/5 + 2. 1/5) + 7 =

-1. 2/5 + 7 = -1. 2/5 + 6. 5/5 = 5. 3/5

Б) = (7. 1/13 - 27/13 + 13/26) + (0,2 - 0,08 - 0,02) =

(7. 2/26 - 2. 2/26 + 13/26) + 0,1 =

5 + 13/26 + 0,1 = 5 + 0,5 + 0,1 = 5,6
