Question

6.7×0.36+0.067×44+0.67×2能用简便方法算吗？

这道题能用简便算法吗

Answer 1

=6.7×0.36+6.7×0.44+6.7×0.2
=6.7×（0.36+0.44+0.2）
=6.7×1=6.7
解法分析：提取公因数6.7，利用乘法分配律逆用，按照四则运算法则进行运算，同级运算按顺序计算，不同级运算先算高级运算，所以就可以很快得出结果。

Answer 2

简便计算过程如下，首先将6.7×0.36转化为0.67×3.6，将0.067×44转化为0.67×4.4，然后提取公因式0.67，所以原式=0.67×3.6+0.67×4.4+0.67×2=0.67×（3.6+4.4+2）=0.67×10=6.7

Answer 3

6.7×0.36+0.067×44+0.67×2
=0.67×10×0.36+0.67÷10×44+0.67×2
=0.67×3.6+0.67×4.4+0.67×2
=0.67×（3.6+4.4+2）
=0.67×10
=6.7

Answer 4

能够用简便运算：
6.7×0.36+0.067×44+0.67×2
=6.7×0.36+6.7×0.44+6.7×0.2
=6.7×(0.36+0.44+0.2)
=6.7×1
=6.7

Answer 5

解：原式
=6.7×0.36+6.7×0.44+6.7×0.2

=6.7×（0.36+0.44+0.2）

=6.7×1
=6.7
