Zadanie 1/ str.10

a)

1 3/7 + 2 6/7 = 3 9/7

3/4  + 5/12  = 9/12 + 5/12 = 14/12= 1 2/12 = 1 1/6

4 8/9 + 4 2/3 = 4 8/9 + 4 6/9 = 8 14/9= 9 5/9

 

b)

6 1/6 + 3 3/8 = 6 4/24 + 3 9/24 = 9 13/24

1/2 + 2/3 + 3/4 = 6/12 + 8/12 + 9/12 = 14/12 + 9/12 = 23/12 = 1 11/12

4 + 5 2/5 + 2 1/4 = 4 + 5 5/20 + 2 5/20 = 7 13/20

 

Zadanie.2 / str. 10

a)

10 1/3 - 3 =7 1/3

10 - 7 3/5 = 2 2/5

2 3/8 - 1 5/8 = 1 11/8 - 1 5/8 = 6/8 = 3/4

b)

6/7 - 5/6 = 1/42

2 3/4 - 1 2/3 = 2 9/12 - 1 8/12 = 1 1/12

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

 

c)

8 3/4 - 2 1/8 = 6 5/8

4 4/5 - 1 1/7 = 4 28/35 - 1 5/35 = 3 23/35

8 1/2 - 6 5/7 = 8 7/14 - 6 10/14 = 7 21/14 - 6 10/14 = 1 11/14

 

Myślę,że pomogłam ;)
