Oblicz:

1+ (⅙ + 0,75) × (-1¹₁₁)


Odpowiedź :

1+ (1/6 +3/4) *(-1 1/11)=
= 1+ (4/24+ 18/24) *(- 12/11)=
= 1+ 22/24 * (-12/11)= (skracamy ułamki przez 12)
= 1+ 22/2* (-1/11)=
= 1 - (22/22)=
= (22/22) - (22/22)= 0

1+ (1/6 +3/4) *(-1 1/11)=
= 1+(4/24+18/24)*(-12/11)=
=1+(22/24)*(-12/11)=
=1+(11/12)*(-12/11)=1-1=0
