小数竖式计算的格式怎么写(小数点竖式计算100道)

小数乘法列式计算正确格式?

小数乘法的列式计算格式如下:

```

a1 b1

× a2 b2

------------

b1b2 (第一行的计算结果)

a1b2 (第二行的计算结果)

+ b1a2 (第三行的计算结果)

+ a1a2 (第四行的计算结果)

--------------

结果的小数点位置取第一个因数和第二个因数小数位数之和为位置处。

```

其中,$a1$ 和 $a2$ 是第一个数和第二个数的整数部分,$b1$ 和 $b2$ 是第一个数和第二个数的小数部分。按照上述格式逐位计算,然后将所有行的计算结果相加即可得到最终的答案。最后,确定答案的小数点位置:小数点的位置应该是第一个因数和第二个因数小数位数之和。

2.47除以3.5竖式计算近似数(得数保留两位小数

  • 0·71

一点四除以0.75列竖式计算得数保留两位小数

  • 1.4÷0.75 ≈ 1.8667≈ 1.867≈ 1.9≈ 1.87(保留2位小数)

4除以0.23列竖式计算,保留一位小数

  • 你用400除以23就行了呗

48除以2.3保留一位小数竖式计算

  • 48÷2.3=480 ÷ 23 ≈20.86≈20.9竖式见图:

用竖式计算小数加减法时,为什么要把小数点对齐
