( - 3/5 - 2/3 ) : [ 1/2 - ( - 3/5 ) ] ??? tolong bantuannya yaa. jawabnya pakai cara

( - 3/5 - 2/3 ) : ( 1/2 - ( - 3/5 ))
= ( -9/15 - 10/15 ) : ( 1/2 + 3/5 )
= -19/15 : ( 5/10 + 6/10 )
= -19/15 : 11/10
= -19/15 x 10/11
= -190/165
= -1 25/165
= -1 5/33

 (-3/5 -2/3) : [ 1/2 -(-3/5)]= ( -15/15 - 10/15): ( 5/10 + 6/10)= - 25 /15: 11/10
                                       = -25/15 x 10/11= -50/33
