Answer 1

Odpowiedź:

a)

1/2 + 1 5/6 = 3/6 + 1 5/6 = 1 8/6 = 2 2/6 = 2 1/13

2/3 + 1 5/6 = 4/6 + 1 5/6 = 1 9/6 = 2 3/6 = 2 1/2

2 1/12 + 1 5/6 = 2 1/12 + 1 10/12 = 3 11/12

1 3/4 + 1 5/6 = 1 9/12 + 1 10/12 = 2 19/12 = 3 7/12

1 1/5 + 1 5/6 = 1 6/30 + 1 25/30 = 2 31/30 = 3 1/30

2 7/8 + 1 5/6 = 2 1/24 + 1 20/24 = 3 21/24

3 4/9 + 1 5/6 = 3 8/18 + 1 15/18 = 4 23/18 = 5 5/18

2.

1 9/10 - 3/5 = 1 9/10 - 6/10 = 1 3/10

2 1/15 - 3/5 = 2 1/15 - 9/15 = 1 16/15 - 9/15 = 1 7/15

1 1/3 - 3/5 = 1 5/15 - 9/15 = 20/15 - 9/15 = 11/15

3/4 - 3/5 = 15/20 - 12/20 = 3/20

4 1/2 - 3/5 = 4 5/10 - 6/10 = 3 15/10 - 6/10 = 3 9/10

5 7/10 - 3/5 = 5 7/10 - 6/10 = 5 1/10

1 3/7 - 3/5 = 1 15/35 - 21/35 = 50/35 - 21/35 = 29/35
