#-6.3bar(3) = - 6 1/3#

Explanation:

Let #x=-6.3bar3#
therefore
#color(white)("XXX")10x = -63.3bar3#
and
#{: (,10x,=,color(white)(-)-63.3bar3),(-,color(white)("0")1x,=,-(-color(white)(".")6.3bar3)) :}#
#underline(color(white)("XXXXXXXXXXXXXXXXX")#
#{: (color(white)(-),color(white)(0)9x,=,color(white)("XXXX")-57) :}#

#rArr x= -57/9 = -19/3 = -6 1/3#
