Szczegółowe wyjaśnienie:

a)

3/5 + 7/10 = 6/10 + 7/10 = 13/10 = 1 i 3/10

4/5 - 4/15 = 12/15 - 4/15 = 8/15

11/30 + 1/6 = 11/30 + 5/30 = 16/30 = 8/15

b)

2 - 5/11 = 22/11 - 5/11 = 17/11 = 1 i 6/11

8 - 1 3/4 = 32/4 - 7/4 = 25/4 = 6 i 1/4

12 - 4 1/9 = 108/9 - 37/9 = 71/9 = 7 i 8/9

c)

2 4/7 - 1 1/2 = 2 i 8/14 - 1 i 7/14 = 1 i 1/14

12 2/3 + 1 3/4 = 12 i 8/12 + 1 i 9/12 = 13 i 17/12 = 14 i 5/12

8 1/8 - 2/3 = 8 i 3/24 - 16/24 = 7 i 27/24 - 16/24 = 7 i 11/24

d)

6 1/4 - 3 5/6 = 6 i 3/12 - 3 i 10/12 = 5 i 15/12 - 3 i 10/12 = 2 i 5/12

7 1/6 + 6 1/8 = 7 i 8/48 + 6 6/48 = 13 i 14/48 = 13 i 7/24

6 1/3 - 3 5/6 = 6 i 2/6 - 3 i 5/6 = 5 i 8/6 - 3 i 5/6 = 2 i 3/6 = 2 i 1/2
