{tex}-{2\over 3} \times {3\over 5} +{5\over 2}-{3\over 5} \times {1\over 6}{/tex}

{tex}-{2\over 3} \times {3\over 5}-{3\over 5} \times {1\over 6} +{5\over 2} {/tex}

Using distributive property of multiplication,

{tex}= {3\over 5}\times \left ( -{2\over 3}-{1\over 6}\right ) +{5\over 2} {/tex}

{tex}= {3\over 5}\times \left ({ -4-1\over 6}\right ) +{5\over 2} {/tex}

 

{tex}= {3\over 5}\times { -5\over 6} +{5\over 2} {/tex}

{tex}-{1\over 2} + {5\over 2}{/tex}

{tex}= {-1+5\over 2} = {4\over 2}{/tex}

= 2
