\(C=-66\times(\frac{1}{2}-\frac{1}{3}+\frac{1}{11})+124\times-37+63\times-124\)

\(C=-66\times\frac{17}{66}-124\times100\)

\(C=-12417\)

#)Giải :

\(C=\left(-66\right).\left(\frac{1}{2}-\frac{1}{3}+\frac{1}{11}\right)+124.\left(-37\right)+63.\left(-124\right)\)

\(C=\left(-66\right).\frac{17}{66}-4699-7812\)

\(C=\left(-17\right)-4699-7812\)

\(C=-12528\)

C = -66.(1/2 - 1/3 + 1/11) + 124.(-37) + 63.(-124)

C = -66.(1/2 - 1/3 + 1/11) - 124.37 - 63.124

C = -17 - 4588 - 7812

C = -12417

C=-66.(\(\dfrac{1}{2}-\dfrac{1}{3}\)+\(\dfrac{1}{11}\))+124.(-37)+63.-124

=-66.\(\dfrac{17}{66}\)-4699-7812=-17-4699-7812=-12528

chúc bạn học tốt nhaNguyễn Thái Nghĩa

C=-66.(1/2-1/3+1/11)+124.(-37)+63.(-124)

C=-66.17/66-124.(37+63)

C=-17-124.100

C=-12417

\(-66.\left(\dfrac{1}{2}-\dfrac{1}{3}+\dfrac{1}{11}\right)+124.\left(-37\right)+63.\left(-124\right)\)

\(=-66.\dfrac{17}{66}+124.\left(-37-63\right)\)

\(=-17+124.\left(-100\right)=-17-12400\)

\(=-12417\)

Tính :

-66 . ( \(\dfrac{1}{2}-\dfrac{1}{3}+\dfrac{1}{11})\)+ 124 . (-37) + 63 . (-124)

= -66 . (\(\dfrac{33}{66}-\dfrac{22}{66}+\dfrac{6}{66}\))+ (-4588) + (-7812)

= -66 . \(\dfrac{17}{66}\)+ (-12400)

= -17 + (-12400)

= -12417
