Answer 1

Odpowiedź:

3 1/3 + 2 10/15 = 3 5/15 + 2 10/15 = 5 15/15 = 16

3 4/15 + 1 11/20 = 3 16/60 + 1 33/60 = 4 49/60

2 7/30 + 1 17/20 = 2 14/60 + 1 51/60 = 3 65/60 = 4 5/60

2 1/6 - 1 = 1 1/6

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

4 - 2 1/3 = 1 2/3

4 - 2 1/2 = 1 1/2

4 - 3 5/7 = 2/7

12 3/4 - 7 5/6 = 12 9/12 - 7 10/12 = 11 21/12 - 7 10/12 = 4 11/12

36/35 - 5/7 = 36/35 - 25/35 = 11/35

5 3/10 -2 4/5 = 5 3/10 - 2 8/10 = 4 13/10 - 2 8/10 = = 2 5/10
