请问各位：1.25乘67.875+125乘6.7825+1.25乘53.875 怎样简便计算（最好有过程哟！）谢谢

1.25×67.875+125×6.7825+1.25×53.875＝125×0.67875+125×6.7825+125×0.53875＝125×（0.67875+6.7825+0.53875）＝125*8＝1000

1.25X67.875+1.25X678.25+1.25X53.785
=1.25X(67.875+678.25+53.785)
=1.25X799.91
=999.8875

把125乘6.7825的125小数点向左移动两位,6.7825的小数点向右移动两位,再用乘法分配律

2楼的错了

1.25*67.875+125*6.7825+1.25*53.875=1.25*（67.875+678.25+53.875）=1.25*800=1000

拿计算机计算最简便。。。
