Answer 1

6/27+4=4 6/27=4 2/9
6 4/9+5 2/9=11 6/9=11 2/3
4 13/17+5 4/17=9 17/17=10
3 8/11+2 6/11=5 14/11=6 3/11
11 8/11-3 5/11=8 3/11
12 19/44-6 37/44=11 63/44-6 37/44=5 26/44= 5 13/22
1-16/21=21/21-16/21=5/21
5-2 3/8= 4 8/8-2 3/8=2 5/8
8 4/9-3 7/9=7 13/9-3 7/9=4 6/9=4 2/3

Answer 2

Давайте поочередно выполним данные операции:

1. 6/27 + 4 6/9 = 6/27 + 46/9 = (2/9) + (46/9) = 48/9 = 16/3
2. 16/3 + 5 2/9 = 16/3 + 47/9 = (16/3) + (47/9) = 151/9
3. 151/9 + 4 13/17 = 151/9 + 79/17 = (151/9) + (79/17) ≈ 8791/153 ≈ 57 20/153
4. 57 20/153 + 5 4/17 = 57 20/153 + 89/17 = (57 20/153) + (89/17) ≈ 3831/68 ≈ 56 43/68
5. 56 43/68 + 3 8/11 = 56 43/68 + 131/11 = (56 43/68) + (131/11) ≈ 7701/68 ≈ 113 25/68
6. 113 25/68 - 3 5/11 = 113 25/68 - 38/11 = (113 25/68) - (38/11) ≈ 6887/68 ≈ 101 19/68
7. 101 19/68 - 12 19/44 = 101 19/68 - 541/44 = (101 19/68) - (541/44) ≈ 5155/68 ≈ 75 35/68
8. 75 35/68 - 6 37/44 = 75 35/68 - 149/44 = (75 35/68) - (149/44) ≈ 2521/68 ≈ 37 17/68
9. 1 - 16/21 = 21/21 - 16/21 = 5/21
10. 5 - 2 3/8 = 5 - 19/8 = (40/8) - (19/8) = 21/8
11. 8 4/9 - 3 7/9 = 8 4/9 - 34/9 = (73/9) - (34/9) = 39/9 = 4 1/3

Обратите внимание, что во всех операциях я упростил дроби до наименьших выражений и вычислил их.
