Question

The sum of rational number -2/5 and its reciprocal is ???​

Answer 1

$One \: rational \: number =\blue{ \frac{-2}{5} }$

$Second \: rational \: number \\= Reciprocal \:of \: \frac{-2}{5} \\=\pink { \frac{-5}{2}}$

$Sum \: of\:these \:two \: rational \: numbers \\= \blue{ \frac{-2}{5} } + \pink { \frac{(-5)}{2}}\\= \frac{-2}{5} - \frac{5}{2} \\= \frac{-4 - 25}{10} \\= \frac{-29}{10}$

Therefore.,

$\red{Sum \:of\: two \: rational \: numbers}\green {=\frac{-29}{10}}$
