Answer:

\large\underline\mathrm{Solution\:: -}

1)\longrightarrow \dfrac{3}{5} \times \dfrac{2}{9} + \dfrac{1}{14} - \dfrac{2}{9} \times \dfrac{4}{5}

\Rightarrow \dfrac{6}{45} + \dfrac{1}{14} - \dfrac{8}{45}

\Rightarrow \dfrac{84 + 45 - 112}{630}

\Rightarrow \dfrac{129 - 112}{630}

\Rightarrow \dfrac{17}{630}

\therefore  The\ answer\: of\: this\: question\: is\: \dfrac{17}{630}

2)\longrightarrow \dfrac{4}{7} \times \dfrac{2}{5} - \dfrac{3}{6} \times \dfrac{1}{2} + \dfrac{2}{5} \times \dfrac{3}{4}

\Rightarrow \dfrac{8}{35} - \dfrac{3}{12} + \dfrac{6}{20}

\Rightarrow \dfrac{96 - 105 + 126}{420}

\Rightarrow \dfrac{96 + 21}{420}

\Rightarrow \cancel{\dfrac{117}{420}}

\Rightarrow \dfrac{39}{140}

\therefore  The\: answer\: of\: this\: question\:is\:\dfrac{39}{140}

3)\longrightarrow \dfrac{8}{3} \times \dfrac{1}{5} + \dfrac{1}{2} \times \dfrac{8}{3} - \dfrac{2}{5}

\Rightarrow \dfrac{8}{15} + \dfrac{8}{6} - \dfrac{2}{5}

\Rightarrow \dfrac{16 + 40 - 12}{30}

\Rightarrow \dfrac{56 - 12}{30}

\Rightarrow \cancel{\dfrac{44}{30}}

\Rightarrow \dfrac{22}{15}

\Rightarrow  1.466

\therefore  The\ answer \:of \:this\: question\: is\:1.466

4)\longrightarrow \dfrac{- 3}{7} \times \dfrac{1}{2} + \dfrac{2}{3} - \dfrac{3}{7} \times \dfrac{1}{6}

\Rightarrow \dfrac{- 3}{14} + \dfrac{2}{3} - \dfrac{3}{42}

\Rightarrow \dfrac{- 9 + 28 - 3}{42}

\Rightarrow \dfrac {19 - 3}{42}

\Rightarrow \cancel{\dfrac{16}{42}}

\Rightarrow \dfrac{8}{21}

\therefore  The\: answer\: of\: this\: question\: is\: \dfrac{8}{21}

5)\longrightarrow \dfrac{6}{11} \times \dfrac{3}{5} + \dfrac{2}{7} - \dfrac{3}{5} \times \dfrac{2}{11}

\Rightarrow \dfrac{18}{55} + \dfrac{2}{7} - \dfrac{6}{55}

\Rightarrow \dfrac{126 + 110 - 42}{385}

\Rightarrow \dfrac{236 - 42}{385}

\Rightarrow \dfrac{194}{385}

\therefore  The\: answer\: of\: this\: question\: is\: \dfrac{194}{385}
