Ułamki zwykłe! Muszę mieć to na jutro.
4 5/9 + 2 1/3 x 4 1/2=
5 1/7 X 1 4/9 - 6 : 4 2/3=
3 1/2 X ( 2 1/4 - 1 1/2 : 6)=
1 1/5 x 1 2/3 x 1/7 + (1 1/7) do potęgi drugiej=
(2 1/6 - 2/3) do potęgi drugiej - 2 1/5=
10- 2 x (3 1/5 - 2 1/4 x 1/3)=
(7/3 - 5/12 + 1 1/2) : 2 3/4 - 5/6)=

1) = 4 5/9 + 7/3 x 9/2= 4 5/9 + 63/6= 100/18 + 189/18= 289/18 = 16 1/18
2) = 13/63 - 9/7= 13/63 - 81/63= - 68/63
3) = 1/2( 2 1/4 - 1/4)= 1
4) = 2 x 1/7 + 64/49 = 2/7 + 64/49= 14/49 + 64/49= 78/49= 1 29/49
5) = (1 3/6)'2 -2 1/5= 81/36 - 11/5= 9/4 -11/5= 45/20- 44/20=1/20
6) = 10 - 2( 3 1/5 - 3/4)= 10 - 2(3 4/20 - 15/20)= 10 - 2(49/20)=10- 98/20= 10 - 49/10=51/10= 5 1/10
7) niestety nie wiem jak zrobic :(
