1、 写出下表中各数的近似值。
精确到个位 精确到十分位 精确到百分位 精确到千分位
0.7064 1
9.9635 10
0.7
0.71
10.0
9.96
0.706 9.964
2、 求出7.2×0.09积的近似 值
（保留一位小数）
19.4÷12≈
保留两位小数： 19.4÷12≈1.62（元）
像这样的题目，我们要根据实际情况，采“去 尾法”来求出商的近似值方法是在保留整数时， 无论十分位数上的数是多少，一律去掉。
(2)王阿姨用一根25米长的红丝带包装礼盒。 每个礼盒要用1.5米长的丝带，这些红丝带 可以包装几个礼盒？

1、小云家有一块长方形的菜地，面积是68.4 平方米，它的宽是7.2米，长是多少米？ 2、假日里，王老师带同学们去森林公园玩。
19.5÷12＝1.625(元) ≈1.6 (元) 答:平均每个羽毛球1元6角。
3、计算： 4.8÷ 2. 3 （保留一位小数） 3.81 ÷7 （保留两位小数）
4、大显身手
(1)小强的妈妈要将2.5千克香油分装在一些玻璃瓶里， 每个瓶子最多盛0.4千克，需要几个瓶？
2.5÷0.4＝6.25（个）≈7 （个） 答:需要7个瓶。 像这样的题目，我们要根据实际情况，采用“进一法”来 求出商的近似值。方法就是在保留整数时，无论十分位 上的数是多少，一律往整数部分进一。
人教版五年级数学上册《小数除法》同步试题(含答案)
考查目的：学生是否能正确区分有限小数与无限小数。
答案：如下图所示：解析：本题是结合具体实例对小数按位数进行分类。
学习了小数除法以后，小数的范围比以前扩大了，不仅认识了有限小数，还认识了无限小数。
顾名思义，有限小数就是小数部分的位数是有限的小数，无限小数就是小数部分的位数是无限的小数。
识别一个小数是有限小数还是无限小数，关键是看它小数部分的位数是有限的还是无限的，而不是看它的末尾是不是省略号。
这里要注意循环小数（循环小数有两种表示方式）都是无限小数，但无限小数除了循环小数外，还有无限不循环小数。
4．把一个小数的小数点向右移动一位后，比原数多2.88，原数是（）。
考查目的：考查学生根据小数点移动引起小数大小变化的规律，灵活运用小数除法计算解决问题。
答案：0.32解析：本题是运用小数除法计算解决小数点移动问题的综合题。
解答本题时，先要根据小数点移动引起小数大小变化的规律，理解小数点向右移动一位，小数就扩大到原数的10倍，也就是比原数多9倍。
再根据“2.88”与“9倍”的对应关系列式解答。
5．用计算器探索规律。
（1）用计算器计算下面各题，并找出规律。
99.99×1＝（） 99.99×2＝（） 99.99×3＝（）（2）用发现的规律直接写出下面各题的得数。
99.99×4＝（） 99.99×5＝（） 99.99×6＝（）（3）你能用发现的规律接着写出几道像这样的算式吗？试一试。
_____________________ _____________________ __________________ ___考查目的：考查学生用计算器探索规律，以及观察、比较、归纳和推理的能力。
答案：（1）99.99 199.98 299.97（2）399.96 499.95 599.94（3）99.99×7＝699.93 99.99×8＝799.92 99.99×9＝899.91解析：本题是利用计算器探索小数乘法中的规律，需要经历“用计算器计算——观察发现规律——利用规律写得数——根据规律续写算式”的过程。
