眼前小伙伴们关于6.47×0.9 0.647的简便算法？真相简直让人了解，小伙伴们都想要分析一下6.47×0.9 0.647的简便算法？，那么小艾也在网络上收集了一些关于38.76-38.76x0.99简便的一些信息来分享给小伙伴们，为什么上头条 究竟是怎么回事？，希望能给小伙伴们一些参考。

7.29÷0.9÷0.09的简便算法7.29÷0.9÷0.09=7.29*10/9*100/9=729*1/9*10/9=81*10/9=90

你好!27*0.99 =27*(1-0.01) =27*1-27*0.01 =27-0.27 =26.73 打字不易,采纳哦!

6.47*9.9=6.47*(10-0.1)=6.47*10-6.47*0.1=64.7-0.647=64.053

0.65*0.99 =0.65*(1-0.01) =0.65*1-0.65*0.01 =0.65-0.0065 =0.6435

5.47x99x6.47 =99(5.97-0.5)(5.97+0.5) =99(5.97平方 - 0.5平方)

3.46+6.54乘以0.09,没有特别好的简便算法,只能根据运算顺序一步一步计算 题目应该是3.46*0.09+6.54乘以0.09,其简便运算,如下: 3.46*0.09+6.54乘以0.09 =0.09*(3.46+6.54) =0.09*10 =0.9

6.42*0.9 =6.42*(1-0.1) =6.42-0.642 =5.778

32x(1.8x640x0.9) =32x1.8x640x0.9 =64x0.9x640x0.9 =64x9x64x0.9 =576*57.6 =576*48*1.2 =576*(50-2)*1.2 =(28800-1152)*1.2 =27648*(1+0.2) =27648+5529.6 =33177.6

64.07*0.99+0.6407的简便计算 =64.07x0.99+64.07x0.01 =64.07x(0.99+0.01) =64.07x1 =64.07

1. (20+4)*9*0.001 2. 0.2*0.9+0.04*0.9

这篇文章到这里就已经结束了，希望对小伙伴们有所帮助。
