let its numerator be x
then denominator will be 15-x
,according to the question
= x+8/15-x+12=3/4
=x+8/27-x=3/4
=(x+8)4/(27-x)3=0
=4x+32/81-3x=0
=4x+32=0×81-3x
=4x+32=81-3x
=4x-3x=81+32
=x=113
=numerator=113
=denominator=15-113=98
=original equation =113/98
if like it follow me and like it as thanks
