Odpowiedź:

a)   1/3 + 3/4= 4/12 + 9/12= 13/12= 1 i 1/12

     2/3 + 6/7= 14/21 + 18/21= 32/21= 1 i 11/21

      7/8 + 5/6= 21/24 + 20/24= 41/24= 1 i 17/24

b)   5 i 1/4 + 5/6= 5 i 3/12 + 10/12= 5 i 13/12= 6 i 1/12

     1 i 7/9 + 2 i 3/10= 1 i 70/90 + 2 i 27/90= 3 i 97/90= 4 i 7/90

    2 i 7/8 + 3 i 1/6= 2 i 21/24 + 3 i 4/24= 5 i 25/24= 6 i 1/24

c)  8/9-2/5= 40/45- 18/45= 22/45

    7/8 - 4/5= 35/40- 32/40=  3/40

    4 i 5/6 - 1/4= 4 i 10/12- 3/12= 4 i 7/12

d)  6 i 8/9 - 1 i 1/2= 6 i  16/18- 1 i 9/18= 5 i 7/18

    8 i 5/7- 3 i 2/5= 8 i 25/35- 3 i 14/35= 5 i  11/35

   4 i 1/4 - 4 i 1/6= 4 i 3/12- 4 i 2/12= 1/12

Answer 2

Odpowiedź:

7/8 + 5/6 = 21/24 + 20/24 = 41/24 = 1 i 17/24

5 i 1/4 + 5/6 = 5 i 3/12 + 10/12 = 5 i 13/12 = 6 i 1/12

1 i 7/9 + 2 i 3/10 = 1 i 70/90 + 2 i 27/90 = 3 i 97/90 = 4 i 7/90

2 i 7/8 + 3 i 1/6 = 2 i 21/24 + 3 i 4/24 = 5 i 25/24 = 6 i 1/24

8/9 - 2/5 = 40/45 - 18/45 = 22/45

7/8 - 4/5 = 35/40 - 32/40 = 3/40

4 i 5/6 - 1/4 = 4 i 10/12 - 3/12 = 4 i 7/12

6 i 8/9 - 1 i 1/2 = 6 i 16/18 - 1 i 9/18 = 5 i 7/18

8 i 5/7 - 3 i 2/5 = 8 i 25/35 - 3 i 14/35 = 5 i 11/35

4 i 1/4 - 4 i 1/6 = 4 i 3/12 - 4 i 2/12 = 1/12
