问题描述:

(13又2/3)÷5+(5又1/3)÷5+(196又3/7)×1/5-(+76又3/7)÷(-5)=

=41/3÷5+16/3÷5+(196又3/7)×1/5+(76又3/7)×1/5
=57/3÷5+(272又3/7)×1/5
=19×1/5+(272又3/7)×1/5
=19/5+272/5+3/35
=291/5+3/35
=2040/35
=408/7


(13又2/3)÷5+(5又1/3)÷5+(196又3/7)×1/5-(+76又3/7)÷(-5)
=(13又2/3)÷5+(5又1/3)÷5+(196又3/7)÷5+(+76又3/7)÷5
=(13又2/3+5又1/3+196又3/7+76又3/7)÷5
=(13又2/3+5又1/3+196又3/7+76又3/7)÷5
=292÷5
