  1. 一个数除以小数

  2. 307 1、说说去掉下列各数的小数点后，原数扩大多少倍？ 402 142 5 8007 30.7 4.02 14.2 8.007 0.005

  3. 填写下表 2 600 180 被除数与除数同时扩大或缩小相同的倍数,商不变

  4. 填空 21 63 6.3 ÷ 0.3=( ) ÷3=( ) 45 225 22.5 ÷ 0.5=( ) ÷5=( ) 1100 11 ÷ 0.02=( ) ÷2=( ) 550

  5. 除数是小数的除法,先移动除数的小数点,使它变为整数,除数的小数点向右移动几位,被除数的小数点也向右移动几位,然后按除数是整数的方法进行计算.

  6. 除数扩大到原来的100倍

  7. 小数除法的计算方法: 二、把除数和被除数的小数点同时向右移动相同的位数，使除数变成整数。当被除数位数不足时，用“0”补足。 一、看清除数有几位小数 三、按照除数是整数的小数除法的方法计算。
