Ответ:

1) 2,5

2) 3

Пошаговое объяснение:

1) 5 7/15 - (7 1/12 - (4 29/60 - (2 1/5 - 1 5/6)))

1. 2 1/5 - 1 5/6 = 11/5 - 11/6 = 66/30 - 55/30 = 11/30

2. 4 29/60 - 11/30 = 269/60 - 11/30 = 269/60 - 22/60 = 247/60

3. 7 1/12 - 247/60 = 85/12 - 247/60 = 425/60 - 247/60 = 178/60

4. 5 7/15 - 178/60 = 82/15 - 178/60 = 328/60 - 178/60 = 150/60 = 2 5/10 = 2,5

2) 6 13/24 - ((14 7/24 - 10 31/48) - (2 3/4 - 1 7/12)) - 1 1/16

1. 14 7/24 - 10 31/48 = 343/24 - 511/48

= 175/48

2. 2 3/4 - 1 7/12 = 33/12 - 19/12 = 14/12

3. 175/48 - 14/12 = 175/48 - 56/48 =

119/48

4. 6 13/24 - 119/48 = 314/48- 119/48 =

195/48 = 65/16

5. 65/16 - 1 1/16 = 65/16 - 17/16 = 48/16 = 3
