Question

0.5*3.22*0.6的简便算法？

Answer 1

0.5x3.22x0.6
=0.5x0.6x3.22
=0.3x3.22
=0.966
运用了乘法交换律和乘法结合律，做起来比较简便。

Answer 2

变换位置0.5*0.6*3.22
＝0.3*3.22
＝0.966

Answer 3

0.5×3.22×0.6
=0.5×0.6×3.22
=0.3×3.22
=0.966

Answer 4

0.5*3.22*0.6的简便算法？
0.5*3.22*0.6
=（0.5*0.6）*3.22
=0.3*3.22
=0.966

Answer 5

0.5X3.22X0.6
=0.3X3.22
=0.966
