1.Oblicz iloczyn 5razy 3 i 2/7 na dwa sposoby :
2.Uzupełnij :
a)6razy .../13=12/13
b).../77 razy=56/77
c)...razy9/23=36/23
d)5razy .../29=30/29

1.
5* 3 2/7 = 5*3 + 5*2/7 = 15 + 10/7 = 15 + 1 3/7 = 16 3/7
5* 3 2/7 = 5* 23/7 = 115/7 = 16 3/7
2.
a)6razy 2/13=12/13
b).../77 razy ????=56/77 brakuje prze ile mnożymy
c)4.razy9/23=36/23
d)5razy 6/29=30/29
1.
5* 3 2/7 = 5*3 + 5*2/7 = 15 + 10/7 = 15 + 1 3/7 = 16 3/7
5* 3 2/7 = 5* 23/7 = 115/7 = 16 3/7
