`(11/6 -5/8) xx 3/5 + 2/5 : 14/15`
`= (88/48-30/48) xx 3/5 + 2/5 xx 15/14`
`= 58/48xx 3/5 + 2/5 xx 15/14`
`=29/24 xx 3/5 + 2/5 xx 15/14`
`= 29/40+3/7`
`=323/280`
\(\left(\dfrac{29}{24}\right).\dfrac{3}{5}+\dfrac{3}{7}\) = \(\dfrac{29}{40}+\dfrac{3}{7}=\dfrac{323}{280}\)
\(\left(\dfrac{11}{6}-\dfrac{5}{8}\right).\dfrac{3}{5}+\dfrac{2}{5}:\dfrac{14}{15}\)
\(=\left(\dfrac{11.4}{6.4}-\dfrac{5.3}{8.3}\right).\dfrac{3}{5}+\dfrac{2}{5}.\dfrac{15}{14}\)
\(=\left(\dfrac{44}{24}-\dfrac{15}{24}\right).\dfrac{3}{5}+\dfrac{2}{5}.\dfrac{15}{14}\)
\(=\dfrac{29}{24}.\dfrac{3}{5}+\dfrac{2}{5}.\dfrac{15}{14}\)
\(=\dfrac{29}{40}+\dfrac{3}{7}\)
\(=\dfrac{323}{280}\).
\(\left(\dfrac{11}{6}-\dfrac{5}{8}\right)\times\dfrac{3}{5}+\dfrac{2}{5}:\dfrac{14}{15}=\left(\dfrac{33}{24}-\dfrac{20}{24}\right)\times\dfrac{3}{5}+\dfrac{2}{5}\times\dfrac{15}{14}=\dfrac{13}{24}\times\dfrac{3}{5}+\dfrac{30}{54}=\dfrac{39}{120}+\dfrac{30}{54}=\dfrac{13}{40}+\dfrac{5}{9}=\dfrac{117}{450}+\dfrac{200}{450}=\dfrac{317}{450}\)
