$\implies \large {\red{ \red{Find \: the \: sum \: of \: \frac{ - 8}{9} \: and \: \frac{ - 4}{57}. }}}$

$\implies \large{ \green{ \sf{To \: find \: the \: sum \: of \: \frac{ - 8}{9} \: and \: \frac{ - 4}{57} we \: have \: to \: add \: it.}}}$

$\implies \large{ \green{ \sf{Take \: the \: LCM \: of \: 9 \: and \: 57.}}}$

$\implies \large{ \green{ \sf{LCM = 171}}}$

$\implies \large{ \green{ \sf{ \frac{ - 152 +( - 12) }{171} }}}$

$\implies \large{ \green{ \sf{ \frac{ - 152 - 12}{171} }}}$

$\implies \large{ \green{ \sf{ \frac{ - 164}{171} }}}$

$\implies \large{ \red{ \sf{So \: its \: answer \: is \: \frac{ - 164}{171} .}}}$
