Пошаговое объяснение:
№1
1) 21 7/96 - 8 5/24 = 21 7/96 - 8 20/96 = 20 103/96 - 8 20/96 = 12 83/96
2) 12 83/96 - 3 1/16 = 12 83/96 - 3 6/96 = 9 77/96
№2
1) 18 5/6 - 5 4/9 = 18 15/18 - 5 8/18 = 13 7/18
2) 13 7/18 - 2 1/2 = 13 7/18 - 2 9/18 = 12 25/18 - 2 9/18 = 10 16/18 = 10 8/9
№3
1) 9 7/24 - 2 9/40 = 9 35/120 - 2 27/120 = 7 8/120 = 7 1/15
2) 7 1/15 - 1 5/36 = 7 12/180 - 1 25/180 = 6 192/180 - 1 25/180 = 5 167/180
№4
1) 20 2/9 - 7 3/5 = 20 10/45 - 7 27/45 = 19 55/45 - 7 27/45 = 12 28/45
2) 12 28/45 - 2 7/45 = 10 21/45 = 10 7/15
№5
1) 16 13/90 - 8 11/45 = 16 13/90 - 8 22/90 = 15 103/90 - 8 23/90 = 7 80/90 = 7 8/9
2) 7 8/9 - 3 4/15 = 7 40/45 - 3 12/45 = 4 28/45
№6
1) 35 11/36 - 9 2/9 = 35 11/36 - 9 8/36 = 26 3/36 = 26 1/12
2) 26 1/12 - 5 7/12 = 25 13/12 - 5 7/12 = 20 6/12 = 20 1/2
