Answer 1

Пошаговое объяснение:

№1

1) 9 - 2/3 = 8 3/3 - 2/3 = 8 1/3

2) 8 1/3 + 6 7/24 = 8 8/24 + 6 7/24 = 14 15/24 = 14 5/8

3) 14 5/8 - 2 1/4 = 14 5/8 - 2 2/8 = 12 3/8

№2

1) 8 13/30 + 13 4/5 = 8 13/30 + 13 24/30 = 21 37/30

2) 21 37/30 - 5 5/6 = 21 37/30 - 5 25/30 = 16 12/30 = = 16 2/5

3) 16 2/5 + 7/10 = 16 4/10 + 7/10 = 16 11/10 = 17 1/10

№3

1) 17 3/4 - 9 1/32 = 17 24/32 - 9 1/32 = 8 23/32

2) 8 23/32 + 4 3/8 = 8 23/32 + 4 12/32 = 12 35/32

3) 12 35/32 - 5 3/16 = 12 35/32 - 5 6/32 = 7 29/32
