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

3) 14 15/24 - 2 1/4 = 14 15/24 - 2 6/24 = 12 9/24 = 12 3/8

№2

1) 8 13/30 + 13 4/5 = 8 13/30 + 13 24/30 = 21 37/30 = 22 7/30

2) 22 7/30 - 5 5/6 = 17 2/6 = 17 1/3

3) 17 1/3 + 7/10 = 17 10/30 + 21/30 = 17 31/30 = 18 1/30

№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

№4

1) 21 4/15 + 1 5/6 = 21 8/30 + 1 25/30 = 22 33/30

2) 22 33/30 - 9 7/30 = 13 26/30 = 13 13/15

3) 13 13/15 + 16 7/24 = 13 104/120 + 16 35/120 = 29 139/120 = 30 19/120

Пошаговое объяснение:

1. 9 - 2/3 + 6 7/24 - 2 1/4 = 12 3/8

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. 8 13/30 + 13 4/5 - 5 5/6 + 7/10 = 17 1/10

1) 8 13/30 + 13 4/5 = 8 13/30 + 13 24/30 = 21 37/30 = 22 7/30

2) 22 7/30 - 5 5/6 = 22 7/30 - 5 25/30 = 21 37/30 - 5 25/30 =

= 16 12/30 = 16 4/10

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

3. 17 3/4 - 9 1/32 + 4 3/8 - 5 3/16 = 7 29/32

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 = 13 3/32

3) 13 3/32 - 5 3/16 = 13 3/32 - 5 6/32 = 12 35/32 - 5 6/32 =  7 29/32

4. 21 4/15 + 1 5/6 - 9 7/30 + 16 7/24 = 30 19/120

1) 21 4/15 + 1 5/6 = 21 8/30 + 1 25/30 = 22 33/30

2) 22 33/30 - 9 7/30 = 13 26/30 = 13 13/15

3) 13 13/15 + 16 7/24 = 13 104/120 + 16 35/120 = 29 139/120 = 30 19/120
