Answer 1

[Nguyễn Thị Thương Hoài]

   \(\dfrac{34}{27}\) : \(\dfrac{51}{18}\) + \(\dfrac{3}{4}\) : \(\dfrac{5}{8}\)

=  \(\dfrac{34}{27}\) x \(\dfrac{18}{51}\) + \(\dfrac{3}{4}\) x \(\dfrac{8}{5}\)

=  \(\dfrac{4}{9}\) + \(\dfrac{6}{5}\)

= \(\dfrac{20}{45}\) + \(\dfrac{54}{45}\)

 =  \(\dfrac{74}{45}\)
