Пошаговое объяснение:

А)

1) 8/15 + 2/3 = 8/15 + 10/15 = 18/15 = 1 3/15

2) 1 3/15 + 11/15 = 1 14/15

Б)

1) 5/9 + 2/7 = 35/63 + 18/63 = 53/63

2) 3/7 + 53/63 = 27/63 + 53/63 = 80/63 = 1 17/63

В)

(5/16 + 19/32) + 11/16 + 25/32 =

5/16 + 19/32 + 11/16 + 25/32 =

(5/16 + 11/16) + (19/32 + 25/32) =

16/16 + 44/32 = 1 + 11/8 = 1 + 1 3/8 = 2 3/8

Answer 2

А) (8/15 + 2/3) + 11/15 = (8/15 + 10/15) + 11/15 = 18/15 + 11/15 = 29/15 = 1 14/15

Б) 3/7 + (5/9 + 2/7) = 27/63 + (35/63 + 18/63) = 27/63 + 53/63 = 80/63 = 1 17/63

В) (5/16 + 19/32) + 11/16 + 25/32 = 5/16 + 19/32 + 11/16 + 25/32 = (5/16 + 11/16) + (19/32 + 25/32) = 16/16 + 44/32 = 1 + 11/8 = 1 + 1 3/8 = 2 3/8
