用简便算法解这道题

765*213/27+765*327/27
=765*(327+213)/27
=765*540/27
=15300

765×213 / 27＋765×327 / 27
=765/27×(213+327)
=765×540/27
=765×20
=15300

765*213/27+765*327*27
=765*(213/27+327*27)
=765*(213/27+8829)
=765*(79532/9)
=6760220

注意加号后面的是乘27!

765×213 / 27＋765×327 / 27
=765/27×(213+327)
=765×540/27
=765×20
=15300

=765/27×(213+327)
=765×540/27
=765×20
=15300

6760220(这个对的，我用计算机算过）
