Помогите пожалуйста мне решить

Answer 1

5)

3 1/8 : 15/16 - 1/4 = 25/8 * 16/15 - 1/4 = 10/3 - 1/4 = 40/12 - 3/12 = 37/12 = 3 1/12

6)

1 9/35 : (1 1/5 + 2/3) = 44/35 : (1 3/15 + 10/15) = 44/35 : 1 13/15 = 44/35 : 28/15 = 44/35 * 15/28 = 33/49

7)

(11 5/8 + 7 1/6) : 3 5/12 = (11 15/24 + 7 4/24) : 41/12 = 18 19/24 : 41/12 = 451/24 * 12/41 = 11/2 = 5,5

8)

(8 7/12 - 2 5/8) : 2 1/6 = (8 14/24 - 2 15/24) : 13/6 = (7 38/24 - 2 15/24) * 6/13 = 5 23/24 * 6/13 = 143/24 * 6/13 = 11/4 = 2 3/4 = 2,75
