73.4X0.2十7.34Ⅹ8.8怎么简便计算？

Answer 1

通过观察可以看到73.4是7.34的10倍，那么把73.4×0.2化成7.34×2，或者把7.34×8.8化成73.4×0.88都是可以的。
73.4×0.2+73.4×0.88
=73.4×（0.2+0.88）
=73.4×1.08
=79.272

Answer 2

=73.4×0.2+73.4×0.88
=73.4×（0.2+0.88）
=73.4×1.08
=79.272
解法分析：能提取公因数，提取公因数，利用乘法分配律逆用，按照四则运算法则进行运算，有括号先算括号里面的，然后就可以很快得出结果。

Answer 3

关于算式73.4×0.2+7.34×8.8的简便计算，详细的操作过程如下：
73.4×0.2+7.34×8.8
=7.34×2+7.34×8.8
=7.34×（2+8.8）
=7.34×10.8
=79.272

Answer 4

计算如下：
73.4X0.2十7.34Ⅹ8.8
=73.4X0.2十73.4Ⅹ0.88
=73.4×(0.2+0.88)
=73.4×1.08
=79.272
