LUDZIE NA JUŻ ! MUSZĘ MIEĆ TO ZA 10 MINUT ! BŁAGAM WAS POMÓŻCIE

a)-1 1\2 + (3\4) : (-2 1\4
b) 7 1\2 - (-2 1/3) * (-4 1/2)
daje najjjj

Answer 1

a)-1 1\2 + (3\4) : (-2 1\4) = - 3/2 + 3/4 : (- 9/4) = - 3/2 + 3/4 * (- 4/9) [skracamy 9 z 3 i 4 z4] = - 3/2 + 1 * (- 1/3) = - 3/2 + (- 1/3) = - 3/2 /*3 - 1/3 /*2 = - 9/6 - 2/6 = - 7/6 = - 1 1/6

b) 7 1\2 - (-2 1/3) * (-4 1/2) = 15/2 + 7/3 * (- 9/2) = 15/2 + (- 63/6) = 15/2 /*3 - 63/6 = 45/6 - 63/6 = - 18/6 = - 3

Answer 2

A) -1 1/2+(3/4):(-2 1/4)=
-3/2+3/4:(-9/4)=
-3/2+3/4*(-4/9)=
-3/2-1/3=
-9/6-2/6=-11/6=-1 5/6
b) 7 1/2-(-2 1/3)*(-4 1/2)=
15/2+7/3*(-9/2)=
15/2-21/2=-6/2=-3
