Answer 1

Пошаговое объяснение:

№1

1) 97 + 4/27 = 97 4/27

2) 97 4/27 - 11 4/27 = 86

3) 86 - 5 4/9 = 85 9/9 - 5 4/9 = 80 5/9

4) 80 5/9 - 11 1/6 = 80 10/18 - 11 3/18 = 69 7/18

5) 69 7/18 - 68 4/9 = 69 7/18 - 68 8/18 = 68 25/18 - 68 8/18 = 17/18

6) 17/18 + 10 5/9 = 17/18 + 10 10/18 = 10 27/18 = 11 9/18 = 11 1/2

№2

1) 7/24 + 17/24 = 24/24 = 1

2) 1 - 13/33 = 33/33 - 13/33 = 20/33

3) 20/33 + 1 10/11 = 20/33 + 1 30/33 = 1 50/33 = 2 17/33

4) 97 21/22 - 2 17/33 = 97 63/66 - 2 34/66 = 95 29/66

5) 95 29/66 - 11 17/22 = 95 29/66 - 11 51/66 = 94 95/66 - 11 51/66 = 83 44/66 = 83 2/3

6) 83 2/3 - 72 = 11 2/3
