Answer 1

[Matt Nguyễn]

$= (\dfrac{48}{30} + \dfrac{25}{30} ) : \dfrac{7}{6}$

$= \dfrac{73}{30} : \dfrac{7}{6}$

$= \dfrac{73}{30} \times \dfrac{6}{7}$
$= \dfrac{438}{210}$

$= \dfrac{73}{35}$

Answer 2

[Trần Huỳnh Uyển Nhi]

\(\left(\dfrac{8}{5}+\dfrac{5}{6}\right):\dfrac{7}{6}\)

\(=\left(\dfrac{48}{30}+\dfrac{25}{30}\right):\dfrac{7}{6}\)

\(=\dfrac{73}{30}:\dfrac{7}{6}\)

\(=\dfrac{73}{30}\times\dfrac{6}{7}\)

\(=\dfrac{438}{210}\)

\(=\dfrac{73}{35}\)
