五年级小数乘除法口算
五年级上册数学小数乘除法口算练习题 (含答案)
答卷时应注意事项１、拿到试卷，要认真仔细的先填好自己的考生信息。
２、拿到试卷不要提笔就写，先大致的浏览一遍，有多少大题，每个大题里有几个小题，有什么题型，哪些容易，哪些难，做到心里有底；３、审题，每个题目都要多读几遍，不仅要读大题，还要读小题，不放过每一个字，遇到暂时弄不懂题意的题目，手指点读，多读几遍题目，就能理解题意了；容易混乱的地方也应该多读几遍，比如从小到大，从左到右这样的题；４、每个题目做完了以后，把自己的手从试卷上完全移开，好好的看看有没有被自己的手臂挡住而遗漏的题；试卷第１页和第２页上下衔接的地方一定要注意，仔细看看有没有遗漏的小题；５、中途遇到真的解决不了的难题，注意安排好时间，先把后面会做的做完，再来重新读题，结合平时课堂上所学的知识，解答难题；一定要镇定，不能因此慌了手脚，影响下面的答题；６、卷面要清洁，字迹要清工整，非常重要；７、做完的试卷要检查，这样可以发现刚才可能留下的错误或是可以检查是否有漏题，检查的时候，1用手指点读题目，不要管自己的答案，重新分析题意，所有计算题重新计算，判断题重新判断，填空题重新填空，之后把检查的结果与先前做的结果进行对比分析。
亲爱的小朋友，你们好! 经过两个月的学习，你们一定有不小的收获吧，用你的自信和智慧，认真答题，相信你一定会闯关成功。

完整版)五年级小数乘除法口算练习题本文是一篇小数乘除法口算练，包括多道口算题目。
由于这些题目都是数字和符号的组合，所以没有明显的段落可以删除或改写。
但是，需要对一些格式错误进行修正，如缺少乘号或除号的地方需要添加符号。
同时，对于一些需要计算的题目，也需要在题目后面添加等于号和计算结果。

1、口算
12÷5：把12扩大10倍是120，120÷5=24；把24缩小到它的十
分之一是2.4，结果是2.4
12÷30：1、把12扩大10倍是120，120÷30=4；把4缩小到它
的十分之一是0..4，结果是0.4。
2、把30缩小到它的十
分之一是3，12÷3=4；把4缩小到它的十分之一是0.4，结果是0.4
=4.8÷0.4 =48÷4 =12
1.6÷0.25
=（1.6×4）÷（0.25×4） =6.4÷1 =6.4

如果：0〈b〈1 时，c○a； b〉1时, c○a；b=1时, c○a。…… 精炼：大大最大，小小最小，大小中间
巩固训练题组：不计算在○里填上〈、〉或=
4.065×2.003○4.065 4.065×0.203○4.065
a×2.58○a×0.58（a>0）
判断下列各题并说明理由
1、两个因数的积一定大于任何一个因数。
学的学习兴趣。
2、笔算：除数是整数的小数除法用竖式计算时方法与
整数出发类似，只不过商中多出了小数点，商的小数点
要与（ 被除数的小数点
）对齐，整数部分不
够商“1”时要用（ 0）补齐整数位不能空缺。例解：
3.28÷24
除数是小数的小数除法用竖式计算时，我们要根据商不
变规律，把除数和被除数同时扩大相同倍数把除数转化
巩固训练题组
（1）、不计算判断下面乘积中一共有几位小数 3.45×0.32 0.0346×0.0067 1.0056×8.008 0.468×0.072 （2）、自己出题看看自己在十分钟内能做对几道题（反复多次 进行、目的是提高计算的速度及准确率）
