#13/2 = 6 1/2#

#5[1/2+ color(red)((cancel3/cancel5 xxcancel5/cancel6_2)) div 5/8]#
#color(white)(xxxxxxx)color(red)(darr)#
#=5[1/2+color(red)(1/2) div5/8]#

#=5[1/2 + color(blue)(1/cancel2 xxcancel8^4/5)]" "larr# multiply by the reciprocal
#color(white)(xxxxxxxxx)color(blue)(darr)#
#=5[1/2" + "color(blue)(4/5)]#
