Answer 1

Пошаговое объяснение:

5 + 2 3/8 = (5+2) + 3/8 = 7 + 3/8 = 7 3/8

12 8/15 - 12 = (12 - 12) + 8/15 = 0 + 8/15 = 8/15

10 4/3 - 7 = (10 - 7) + 4/3 = 3 + 4/3 = 3 + 1 1/3 = (3 + 1) + 1/3 = 4 + 1/3 = 4 1/3

4 1/9 + 3 4/9 = (4 + 3) + (1/9 + 4/9) = 7 + 5/9 = 7 5/9

4 1/6 + 10 = (4 + 10) + 1/6 = 14 + 1/6 = 14 1/6

7 5/7 - 4 3/7 = (7 - 4) + (5/7 - 3/7) = 3 + 2/7 = 3 2/7
