Answer 2

[Nguyễn Thị Hương giang]

a) \(\dfrac{4}{3}\) x \(\dfrac{7}{8}\) x 5

= \(\dfrac{7}{6}\) x 5

=  \(\dfrac{35}{6}\)

b) \(\dfrac{8}{9}x\dfrac{6}{5}:\dfrac{3}{2}\)

= \(\dfrac{16}{15}:\dfrac{3}{2}\)

= \(\dfrac{32}{45}\)

c) \(\dfrac{4}{7}:\dfrac{5}{7}x\dfrac{10}{11}\)

= \(\dfrac{4}{5}x\dfrac{10}{11}\)

= \(\dfrac{8}{11}\)
