Answer 1

1 столбик

a+b = 10 10/7 + 3 1/5 = 80/7 (5) + 16/5 (7) = (400+112)/35 = 512/35 = 14 22/35

a-b = 10 10/7 - 3 1/5 = 80/7 (5) + 16/5 (7) = (400-112)/35 = 288/35 = 8 8/35

2 столбик

b = 14 2/21 - 9 3/7 = 296/21 (1) - 66/7 (3) = (296-198)/21 = 98/21 = 4 14/21

a-b = 9 3/7 - 4 14/21 = 66/7 (3) - 98/21 (1)  = (198-98)/21 = 100/21 = 4 16/21

3 столбик

b = 15 9/10 - 2 3/100 = 159/10 (10) - 203/100 (1) = (1590-203)/100 = 1387/100 = 13 87/100  

a+b = 15 9/10 + 13 87/100 = 159/10 (10) + 1387/100 (1) = (1590+1387)/100 = 2977/100 = 29 77/100

4 столбик

а = 23 - 4 3/5 = 115/5 - 23/5 = (115-23)/5 = 92/5 = 18 2/5

a-b = 18 2/5 - 4 3/5 = 92/5 - 23/5 = 69/5 = 13 4/5

5 столбик

a+b = 5 7/20 + 3 3/10 = 107/20 + 33/10 (2) = (107+66)/20 = 173/20 = 8 13/20

a-b = 5 7/20 - 3 3/10 = 107/20 - 33/10 (2) = (107-66)/20 = 41/20 = 2 1/20

6 столбик

а = 1 5/8 + 6 3/4 = 13/8 + 27/4 (2) = (13+54)/8 = 67/8 = 8 3/8

a+b = 8 3/8 + 1 5/8 = (67+13)/8 = 80/8 = 10

7 столбик

b = 7 3/5 - 4 3/10 = 38/5 (2) - 43/10 = (76-43)/10 = 33/10 = 3 3/10

a-b = 4 3/10 - 3 3/10 = 1
