b) od każdej z podanych liczb odejmij 3/5

1.9/10 | 2.1/5 | 1.1/3 | 3/4 | 4.1/2 | 5.7/20 | 1.3/7 ​

Answer 1

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

Answer 2

Odpowiedź:

Szczegółowe wyjaśnienie:

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

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

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

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

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

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

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=1 50/35 -21/35=1 29/35
