Пошаговое объяснение:

Е)

1. 1/9 + 2,75 + 1/3 =

1. 1/9 + 2. 75/1 00 + 1/3 =

1. 1/9 + 2. 3/4 + 1/3 =

1. 4/36 + 2. 27/36 + 12/36 =

3. 43/36 = 4. 7/36

С)

8,5 + 5/6 - 6,25 =

8. 5/10 + 5/6 - 6. 25/1 00 =

8. 1/2 + 5/6 - 6. 1/4 =

8. 6/12 + 10/12 - 6. 3/12 =

8. 16/12 - 6. 3/12 = 2. 13/12 = 3. 1/12
