A) 7/12+5/12 : 6 -11/36

=7/12 + 5/72 -11/36

=47/72-11/36

=25/72

(-12)+(-13)+36+(-11)=[(-12)+(-13)+(-11)]+36

                             =[-(12+13+11)]+36

                             =(-36)+36

                             =0

Tick cho mình nha !

(-12)+(-13)+36+(-11)=-(11+12+13)+36=-36+36=0

tick mk nha các bạn

(-12) + (-13) + 36 + (-11)

= -(11 + 12 + 13) + 36

= -36 + 36
= 0

Chọn A

-12+(-13)+36+(-11)

=(-12-13-11)+36

=-36+36

=0

b

\(\left(-12\right)+\left(-13\right)+36+\left(-11\right)\)

\(=\left(\left(-12\right)+\left(-13\right)+\left(-11\right)\right)+36\)

\(=\left(-12-13-11\right)+36\)

\(=-36+36\)

\(=0\)

( - 12 ) + ( - 13 ) + 36 + ( - 11 ) 

= 36 + [ (-12) + ( - 13 ) + ( -11 )]

= 36 + ( - 36 )

= 0

( - 12 ) + ( - 13 ) + 36 + ( - 11 )

= [ ( - 12 ) + ( - 13 ) + ( - 11 ) ] + 36

= ( - 36 ) + 36

= 0

k mk nha bnThanks

(-12)+(-13)+36+(-11)

= -12 - 13 + 36 - 11

= - (11+12+13) + 36

= - 36 + 36

= 0

= -25 + 25

= 0 nha 

chuc ban hc tot

(-12)+(-13)+36+(-11)

=-25+36+(-11)

=11+(-11)

=0

a: \(=\dfrac{-6}{11}:\dfrac{3\cdot11}{4\cdot5}=\dfrac{-6}{11}\cdot\dfrac{20}{33}=\dfrac{-2}{11}\cdot\dfrac{20}{11}=\dfrac{-40}{121}\)
