Answer 1

Пошаговое объяснение:

5 1/10 + 8 3/8 = 5 4/40 + 8 15/40 = 13 19/40

6 2/15 + 42 18/25 = 6 10/75 + 42 54/75 = 48 64/75

5 3/18 + 18 1/27 = 5 9/54 + 18 2/54 = 23 11/54

9 3/20 + 7 4/15 = 9 9/60 + 7 16/60 = 16 25/60 = 16 5/12

2 19/44 + 5 52/66 = 2 57/132 + 5 104/132 = 7 161/132 = 8 29/132

38 21/26 + 14 34/39 = 38 63/78 + 14 68/78 = 52 131/78 = 53 53/78

6 11/12 + 3 15/16 = 6 44/48 + 3 45/48 = 9 89/48 = 10 41/48
