    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5\times5}{2\times5} - \dfrac{11\times2}{5\times2})[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{25}{10} - \dfrac{22}{10})[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{25-22}{10})[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2}{11} + \dfrac{4}{11}\times\dfrac{3}{10}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2}{11} + \dfrac{4\times3}{11\times10}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2}{11} + \dfrac{12}{110}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2\times10}{11\times10} + \dfrac{12}{110}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{20}{110} + \dfrac{12}{110}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{20+12}{110}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{32}{110}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{2\times16}{2\times55}[/tex]

    [tex]\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{\not{2}\times16}{\not{2}\times55}[/tex]

    [tex]\boxed{\dfrac{2}{11} + \dfrac{4}{11}\times(\dfrac{5}{2} - \dfrac{11}{5})=\dfrac{16}{55}}[/tex]
