7.3x0.64+9.36的简便算法7.3x0.64+9.36的简便算法7.3x0.64+9.36的简便算法7.3x0.64+9.36=7.3*0.64+(10-0.64)=6.3*0.64+10=4

7.3x0.64+9.36的简便算法
7.3x0.64+9.36的简便算法

7.3x0.64+9.36的简便算法
7.3x0.64+9.36
=7.3*0.64+(10-0.64)
=6.3*0.64+10
=4.032+10
=14.032

7.3乘(0.64+9.36)

7.3×0.64 9.36 =7.3×0.64 1.4x0.64 =8.7x0.64 =7.3X0.8X0.8 11.7X0.8 =(5.84 11.7)0.8 =17.54X0.8 =14.032
