Mik cần gấp nha, giải chi tiết giúp mik

Answer 1

(11 / 29 + 2 / 29 + 16 / 29 ) . 9 / 10

1 . 9/10 = 9/10

Answer 2

\(\dfrac{9}{10}\times\left(\dfrac{11}{29}+\dfrac{2}{29}+\dfrac{16}{29}\right)=\dfrac{9}{10}\times\dfrac{29}{29}=\dfrac{9}{10}\times1=\dfrac{9}{10}\)

Answer 3

= 9/10 x ( 11/29 + 2/9 + 16/29 )

= 9/10 x 1

= 9/10

Answer 4

\(\dfrac{9}{10}\times\left(\dfrac{11}{29}+\dfrac{16}{29}+\dfrac{2}{29}\right)=\dfrac{9}{10}\times\dfrac{29}{29}=\dfrac{9}{10}\times1=\dfrac{9}{10}\)

Answer 5

9/10

Answer 6

11/29 x 9/10 + 2/29 x 9/10 + 16/29 x 9/10

=(11/29+2/29+16/29)+(9/10+9/10+9/10)

=29/29+27/10

=
