\(\dfrac{-5}{12}\times\dfrac{2}{11}+\dfrac{-5}{11}\times\dfrac{9}{11}+\dfrac{5}{12}\\ =\dfrac{5}{12}\times\left(1-\dfrac{2}{11}\right)+\dfrac{-5}{11}\times\dfrac{9}{11}\\ =\dfrac{5}{12}\times\dfrac{9}{11}+\dfrac{-5}{11}\times\dfrac{9}{11}\\ =\dfrac{9}{11}\times\left(\dfrac{5}{12}-\dfrac{5}{11}\right)\\ =\dfrac{9}{11}\times\dfrac{-5}{132}=-\dfrac{15}{484}\)

\(\frac{8}{11}.\frac{14}{23}+\frac{8}{11}.\frac{9}{23}-\frac{8}{11}\)

\(=\frac{8}{11}.\left(\frac{14}{23}+\frac{9}{23}\right)-\frac{8}{11}\)

\(=\frac{8}{11}.1-\frac{8}{11}\)

\(=0\)

=8/11x(14/23+9/23)-8/11

=8/11x23/23-8/11

=8/11x1-8/11

=0

11 x 89 = 979.

15 x 11 =165.

11*89=979

15*11=165

11x89=979

15x11=165

\(\dfrac{9}{11}\) x \(\dfrac{1}{3}\) = \(\dfrac{3}{11}\)

9/33

3/11

k nha

\(11\times1-10=1\)

tíc nha

=1

thương mà k nha

11x1=11

32x7=224

90x2=180

12x42=504

k mk nha!!!

11x1=11

32x7=224

90x2=180

tíck cho mik thì mik sẽ tíck lại 

=11

=224

=180

=504
