5.37×0.66+46.3×0.066简便运算？

Answer 1

答案是6.6。步骤如下，5.37×0.66+46.3×0.066等于5.37×0.66+4.63×0.66=0.66x（5.37+4.63)=0.66×10=6.6。这道题应用了结合率和凑十法。

Answer 2

先把0.66和0.066统一成相同的小数，可以变成5.37×0.066×10+46.3×0.066=53.7×0.066+46.3×0.066=（53.7+46.3）×0.066=100×0.066=6.6

Answer 3

在这个式子中，因为46.3×0.066也就等于4.63×0.66。所以原式可以改为5.37×0.66+4.63×0.66这个式子就可以转化为0.66×（5.37+4.63）=6.6

Answer 4

5.37×0.66+46.3×0.066
＝5.37×0.66+4.63×0.66
＝（5.37+4.63）×0.66
＝10×0.66
＝6.6
简便方法：乘法分配律（a×b）×c＝a×c+b×c

Answer 5

=53.7×0.066+46.3×0.066
=（53.7+46.3）×0.066
=100×0.066
=6.6
