Answer 1

$the \: multiplicative \: inverse \: of \: \frac{ - 5}{12} \: is \\ \\ (a). \: \: \frac{5}{12} \\ \\ (b). \: \: \frac{12}{5} \\ \\ (c). \: \: \frac{ - 12}{5} \\ \\ (d). \: \: \frac{2}{15} \\ \\ ans. \: \: because \: in \: multiplicative \: inverse \: is \: number \: can\: change \: \\ opposite \: but \: + \: and \: - \: sign \: can \: not \: change \: \\ in \: multiplicative \: inverse \\ \\ so \: answer \: is \: option \: (c). \: \frac{ - 12}{5} \\ \\ is \: correct$
