Answer 1

 a) Do każdej z podanych liczb dodaj 1 5/6:

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

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

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 21/24 + 1 20/24 = 3 41/24 = 4 17/24

3 4/9 + 1 5/6 = 3 16/36 + 1 30/36 = 4 46/36 = 5 10/36 = 5 5/18

 

b)Od każdej z podanych liczb odejmij 3/5:

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 7/20 - 3/5 = 5 7/20 - 12/20 = 4 27/20 - 12/20 = 4 15/20 = 4 3/4

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