Answer:

$\huge\fcolorbox{red}{orange}{Solution :-}$

$a)\longrightarrow$ $\dfrac{3}{5} \times \bigg(\dfrac{18}{11} - \dfrac{21}{16}\bigg)$

$\Rightarrow$ $\dfrac{3}{5} \times \bigg(\dfrac{288 - 231}{176}\bigg)$

$\Rightarrow$ $\dfrac{3}{5} \times \bigg(\dfrac{57}{176}\bigg)$

$\Rightarrow$ $\dfrac{171}{880}$

$\therefore$ $The\: answer\: of\: this\: question\: is\: \dfrac{171}{880}$

$b)\longrightarrow$ $\bigg(\dfrac{15}{17} \times \dfrac{(- 34)}{50}\bigg) + \bigg(\dfrac{15}{17} \times \dfrac{- 16}{50}\bigg)$

$\Rightarrow$ $\bigg(\dfrac{- 510}{850}\bigg) + \bigg(\dfrac{- 240}{850}\bigg)$

$\Rightarrow$ $\dfrac{- 510}{850} + \dfrac{- 240}{850}$

$\Rightarrow$ $\dfrac{- 510 - 240}{850}$

$\Rightarrow$ $\cancel{\dfrac{- 750}{850}}$

$\Rightarrow$ $\dfrac{- 15}{17}$

$\therefore$ $The\: answer\: of\: this\: question\: is\: \dfrac{- 15}{17}$

$c)\longrightarrow$ $\bigg(\dfrac{- 23}{51} + \dfrac{16}{102}\bigg) \div \dfrac{12}{102}$

$\Rightarrow$ $\bigg(\dfrac{- 46 + 16}{102}\bigg) \times\dfrac{102}{12}$

$\Rightarrow$ $\dfrac{- 30}{102} \times \dfrac{102}{12}$

$\Rightarrow$ $\cancel{\dfrac{- 3060}{1224}}$

$\Rightarrow$ $\dfrac{5}{2}$

$\Rightarrow$ $2.5$

$\therefore$ $The\: answer\: of\: this\: question\: is\: 2.5\:$

$d)\longrightarrow$ $\dfrac{41}{37} \times \bigg(\dfrac{6}{5}\bigg) - \dfrac{47}{37}$

$\Rightarrow$ $\dfrac{246}{185} - \dfrac{47}{37}$

$\Rightarrow$ $\dfrac{246 - 235}{185}$

$\Rightarrow$ $\dfrac{11}{185}$

$\therefore$ $The\: answer\: of\: this\: question\: is\: \dfrac{11}{185}$

$e)\longrightarrow$ $\dfrac{79}{87} \div \dfrac{148}{3}$

$\Rightarrow$ $\dfrac{79}{87} \times \dfrac{3}{148}$

$\Rightarrow$ $\cancel{\dfrac{237}{12876}}$

$\Rightarrow$ $\dfrac{79}{4292}$

$\therefore$ $The\: answer\: of\: this\: question\: is\: \dfrac{79}{4292}$
