82又2/3×3/8+72又4/5×5/7-63又3/65×5/6
=(82+2/3)x3/8+(72+4/5)x5/7-(63+3/65)x5/6
=(248/3)x3/8+(364/5)x5/7-(4098/65)x5/6
=31+52-(683/13)
=31+52-(52+7/13)
=31+52-52-7/13
=31-7/13
=30+6/13
=396/13
=(82+2/3)x3/8+(72+4/5)x5/7-(63+3/65)x5/6
=(248/3)x3/8+(364/5)x5/7-(4098/65)x5/6
=31+52-(683/13)
=31+52-(52+7/13)
=31+52-52-7/13
=31-7/13
=30+6/13
=396/13
