7.3/4+2.7*0.25的简便算法
问题描述：
7.3/4+2.7*0.25的简便算法
答
7.3/4+2.7*0.25
=7.3*0.25+2.7*0.25
=(7.3+2.7)*0.25
=10*0.25
=2.50.18+4.26-0.18+4.26 0.58*1.3/0.58*1.3简便算法0.18+4.26-0.18+4.26=4.26+4.26=8.520.58*1.3/0.58*1.3=1过程好像不对吧0.18+4.26-0.18+4.26 这个题目有括号没？=4.26+4.26=8.520.58*1.3/0.58*1.3=1.3*1.3=1.69还是这个？(0.58*1.3)/(0.58*1.3)=1
