$\begin{gathered} 2(3)/(4)=(8+3)/(4)=(11)/(4) \\ (11)/(4)mi\to(2)/(5)h \\ xmi\to1h \end{gathered}$

Using cross multiplication:

$\begin{gathered} (11)/((4)/(x))=(2)/(5) \\ x=(11)/(4)\cdot(5)/(2) \\ x=(55)/(8)mi=6(7)/(8)mi \end{gathered}$

Convert a mixed number to a fraction:

$a(c)/(b)=(a\cdot b+c)/(b)$
