每日一练1-5

上海数学：五年级上册总复习知识汇总第二单元小数乘除法1、小数乘整数：意义——求几个相同加数的和的简便运算。

如：1.5×3表示1.5的3倍是多少或3个1.5的和的简便运算.计算方法：先把小数扩大成整数；按整数乘法的法则算出积；再看因数中一共有几位小数，就从积的右边起数出几位点上小数点。

2、小数乘小数：意义——就是求这个数的几分之几是多少。

如：1。

5×0。

8就是求1。

5的十分之八是多少。

1。

5×1.8就是求1。

5的1.8倍是多少.计算方法：先把小数扩大成整数；按整数乘法的法则算出积;再看因数中一共有几位小数，就从积的右边起数出几位点上小数点。

注意：计算结果中，小数部分末尾的0要去掉，把小数化简；小数部分位数不够时，要用0占位.3、规律：一个数（0除外)乘大于1的数，积大于原来的数；一个数（0除外）乘等于1的数,积等于原来的数。

特值法代入一个数（0除外）乘小于1的数，积小于原来的数。

4、求近似数的方法：⑴四舍五入法；⑵进一法；⑶去尾法5、计算钱数，保留两位小数，表示计算到分。

保留一位小数，表示计算到角。

6、小数四则运算顺序跟整数是一样的。

7、运算定律和性质：加法：加法交换律：a+b=b+a 加法结合律：(a+b)+c=a+(b+c）减法：减法性质：a—b—c=a—（b+c) a—（b—c)=a—b+c乘法:乘法交换律：a×b=b×a 乘法结合律:（a×b)×c=a×（b×c）乘法分配律：（a+b)×c=a×c+b×c 【（a—b）×c=a×c-b×c】重点强调除法：除法性质：a÷b÷c=a÷(b×c）8、小数除法的意义：已知两个因数的积与其中的一个因数，求另一个因数的运算.如：0。

6÷0.3表示已知两个因数的积0。

But they are good at dealing with people and problems in the real world. Other people might be book-smart. This means they have spent many years in school. But they may not be so smart when dealing with people or real-world problems.And then there is a definition of smart that means to talk or behave disrespectfully. If you say something disrespectful to your parents, they might say, “Don't get smart with me!” Here, “smart”means showing a lack of respect by saying something unkind. This definition of smart can also be used as a verb. 5. _______A.Do they really mean you are smart?B. The answer is not as easy as you might think.C. People have different attitudes towards being smart.D. In fact, maybe that person is no longer your friend.E. But the most common meaning of “smart” is to be intelligent.F.
