6.4×0.25+3.6÷4简便算法
6.4×0.25+3.6÷4简便算法

6.4×0.25+3.6÷4简便算法
6.4×0.25+3.6÷4
=6.4×1/4+3.6÷4
=6.4÷4+3.6÷4
=（6.4+3.6）÷4
=10÷4
=2.5

先算乘除，后算加减

3.6÷4=3.6×1/4
6.4×0.25=6.4×1/4
所以原式=6.4×1/4+3.6×1/4
=(6.4+3.6)×1/4
=5/2

6.4×0.25+3.6÷4
=6.4×0.25+3.6×0.25
=(6.4+3.6)×0.25
=10×0.25
=2.5

6.4×0.25+3.6÷4
=4*1.6*0.25+9
=4*0.25*1.6+9
=1*1.6+9
=9.6
