Question

8.6✖️5.4➕86✖️0.45➕0.86怎么简算？

Answer 1

这个题目考查的是乘法分配律，不过不能直接用，我们需要对数据进行处理下，使它符合乘法分配律的应用条件。
8.6×5.4+86×0.45+0.86
=8.6×5.4+8.6×4.5+8.6×0.1
=8.6×(5.4+4.5+0.1)
=8.6×10
=86

Answer 2

你好
简便计算过程如下
8.6×5.4+86×0.45+0.86
=8.6×5.4+86×0.1×4.5+8.6×0.1
=8.6×5.4+8.6×4.5+8.6×0.1
=8.6×（5.4+4.5+0.1）
=8.6×10
=86
望采纳

Answer 3

8.6×5.4+86×0.45+0.86=8.6×(5.4+4.5+0.1)=8.6×10=86

Answer 4

86*（54+45+1）*0.01=86*（100*0.01）=86
