Пошаговое объяснение:

№1

1) |-44 4/7| : |-1 31/35| = 44 4/7 : 1 31/35 = 312/7 : 66/35 = 312/7 * 35/66 = 312/1 * 5/66 = 1560/66

2) 1560/66 : |-3 5/33| = 1560/66 : 3 5/33 = 1560/66 : 104/33 = 1560/66 * 33/104 = 15/2 * 1/1 = 15/2 = 7 1/2

3) 7 1/2 + |-20 3/13| = 7 1/2 + 20 3/13 = 7 13/26 + 20 6/26 = 27 19/26

4) 27 19/26 - |-17 8/13| = 27 19/26 - 17 8/13 = 27 19/26 - 17 16/26 = 10 3/26

№2

1) |-23 1/18| : |-9 2/9| = 23 1/18 : 9 2/9 = 415/18 : 83/9 = 415/18 * 9/83 = 5/2 * 1/1 = 5/2

2) 5/2 : |-2 17/54| = 5/2 : 2 17/54 = 5/2 : 125/54 = 5/2 * 54/125 = 1/1 * 27/25 = 27/25 = 1 2/25

3) |-2 18/35| : |-1 13/42| = 2 18/35 : 1 13/42 = 88/35 : 55/42 = 88/35 * 42/55 = 8/5 * 6/5 = 48/25 = 1 23/25

4) 1 2/25 + 1 23/25 = 2 25/25 = 3
