\[\begin{array}{l}
\dfrac{6}{5} - \dfrac{6}{{10}} + \dfrac{4}{{10}}:\dfrac{5}{8}\\
= \dfrac{6}{5} - \dfrac{3}{5} + \dfrac{2}{5}.\dfrac{8}{5}\\
= \dfrac{6}{5} - \dfrac{3}{5} + \dfrac{{16}}{{25}}\\
= \dfrac{3}{5} + \dfrac{{16}}{{25}}\\
= \dfrac{{31}}{{25}}
\end{array}\]
`6/5 - 6/10 + 4/10 : 5/8`
`= 6/5 - 6/10 + 4/10 . 8/5`
`= 6/5 - 6/10 + 32/50`
`= {60-30+32}/50`
`= 62/50=31/25`
