63.2*0.1+6.32*9=(简便计算)

63.2*0.1+6.32*9=(简便计算)
63.2*0.1+6.32*9=(简便计算)

63.2*0.1+6.32*9=(简便计算)
63.2*0.1+6.32*9
=63.2(0.1+0.9)
=63.2*1
=63.2
运用乘法分配律

63.2*0.1+6.32*9
=6.32*1+6.32*9
=6.32*(1+9)
=6.32*10
=63.2

63.2*0.1+6.32*9=63.2*0.1+63.2*0.9=63.2(0.1+0.9)=63.2*1=63.2

63.2*0.1+6.32*9
=63.2(0.1+0.9)
=63.2*1
=63.2

63.2*0.1+6.32*9
=6.32*1+6.32*9=63.2
