7.3/4+2.7*0.25的简便算法7.3/4+2.7*0.25的简便算法7.3/4+2.7*0.25的简便算法7.3/4+2.7*0.25=7.3*0.25+2.7*0.25=(7.3+2.7)*

7.3/4+2.7*0.25的简便算法
7.3/4+2.7*0.25的简便算法

7.3/4+2.7*0.25的简便算法
7.3/4+2.7*0.25
=7.3*0.25+2.7*0.25
=(7.3+2.7)*0.25
=10*0.25
=2.5

7.3/4+2.7*0.25
=(7.3+2.7)/4
=10/4
=2.5

7.3/4+2.7*0.25
=7.3*0.25+2.7*0.25
=(7.3+2.7)*0.25
=10*0.25
=2.5
祝楼主学习更上一层楼
