Ответ: 5 26/75 ; 11 5/6 ; 15 13/36 ; 5 5/36 ; 7 3/8 ; 7 13/60.

Пошаговое объяснение:

1) 3 1/15 + 2 7/25 = 5 26/75

(3+2)+(1/15+7/25)

5+26/75 = 5 26/75

2) 2 7/10 + 9 2/15 = 11 5/6

(2+9)+(7/10+2/15)

11+5/6 = 11 5/6

3) 9 5/18 + 6 1/12 = 15 13/36

(9+6)+(5/18+1/12)

15+13/36 = 15 13/36

4) 1 7/12 + 3 5/9 = 5 5/36

(1+3)+(7/12+5/9)

4+41/36

4+1 5/36

4+1+5/36

5+5/36 = 5 5/36

5) 5 5/24 + 2 1/6 = 7 3/8

(5+2)+(5/24+1/6)

7+3/8 = 7 3/8

6) 3 1/12+4 2/15 = 7 13/60

(3+4)+(1/12+2/15)

7+13/60 = 7 13/ 60
