Answer 1

Пошаговое объяснение:

(5 + 2 3/8) * (4 1/6 + 10) = 7 3/8 * 14 1/6 = 59/8 * 85/6 = 5015/48 = 104 23/48,

9/10 * 5/6 * 40/7 * 14/5 = 4 * 3 = 12,

5/22 * 2/5 - 2/5 * 3/22 + 3/11 = 2/5 * (5/22 - 3/22) + 3/11 =

= 2/5 * 3/22 + 3/11 = 3/55 + 15/55 = 18/55,

(3 1/14 - 2 5/7) * (7 - 6 3/5) = (2 15/14 - 2 10/14) * (6 5/5 - 6 3/5) =

= 5/14 * 2/5 = 2/14 = 1/7,

(1 4/9 + 2 5/6 - 2 3/4) * (2 1/2 - 11/14) =

= (1 16/36 + 2 30/36 - 2 27/36) * (2 7/14 - 11/14) =

= 1 19/36 * (1 21/14 - 11/14) = 1 19/36 * 1 10/14 =

= 55/36 * 24/14 = 110/42 = 2 24/42 = 2 12/21,

(3 1/12 + 1 5/12) : 1 1/2 = 4 6/12 : 1 1/2 = 4 1/2 : 3/2 =

= 9/2 * 2/3 = 9/3 = 3,

3/4 : 5/6 + 2 1/2 * 2/3 - 1 : 10/9 =

= 3/4 * 6/5 + 5/2 * 2/3 - 1 * 9/10 =

= 18/20 + 5/3 - 9/10 = 54/60 + 5/3 - 54/60 = 5/3 = 1 2/3,

7 1/8 : 4 3/8 * 8 = 57/8 : 35/8 * 8 =

= 57/8 * 8/35 * 8 = 57/35 * 8 = 456/35 = 13 1/35
