giúp mình nhanh nhé thank you <3

Answer 1

\(\dfrac{14}{9}\) x \(\dfrac{11}{8}-\dfrac{3}{8}\) x \(\dfrac{14}{9}\)

\(=\dfrac{14}{9}\) x \(\left(\dfrac{11}{8}-\dfrac{3}{8}\right)\)

\(=\dfrac{14}{9}\) x \(\dfrac{8}{8}=\dfrac{14}{9}\) x \(1\)

\(=\dfrac{14}{9}\)

Answer 2

oa cảm ơn bạn nhé :3

Answer 3

14/9 × 11/8 - 3/8 × 14/9 

= 14/9 × ( 11/8 - 3/8 ) 

= 14/9 × 8/8 

= 14/9 - 1 

= 5/9

Answer 4

=14/9 x (11/8-3/8)

=14/9x 8/8

=14/9x1=14/9

Answer 5

14/9 x 11/8 - 3/8 x 14/9

= 14/9 x (11/8-3/8)

= 14/9 x 8/8=14/9 x 1

=14/9
