《小数乘法》练习题及答案.docx

小学五年级数学试卷 《小数乘法》同步试题 湖北省武汉市青山区青山小学张满等(供题) 湖北省武汉市教育科学研究院马青山(整理) 一、填空 1.王阿姨的计算器坏了,显示屏上显示不出小数点,你能很快地帮她写出下面各式的结果吗? 已知: 148× 23= 3404, 那么:1.48 × 23=(),148 × 2.3 =(),0.148 × 23=(),14.8 × 2.3 =(),1.48 × 0.23 =(),0.148 ×0.23 =()。 考查目的:考查学生根据因数与积的小数位数的关系,正确确定积的小数点的位置。 答案: 34.04340.4 3.40434.040.34040.03404 解析:这六道小数乘法的计算方法是相同的,就是积的小数点位置不同。它们都是先按照整数乘法“ 148× 23”算出积,再根据小数乘法中因数与积的小数位数之间的关系,在积“3404”中确定小数点的位置。 确定小数点的位置时,一定要数清两个因数一共有几位小数,再从积的右边起数出几位,点上小数点。本 题既考查了学生对小数乘法计算方法掌握的情况,又让学生感受到小数乘法与整数乘法之间的内在联系。 2.在○里填上“>”“<”或“=”。 7.3 ×1.2 ○ 7.3 4.9 × 0.65○ 4.9 5.43 × 1○ 5.43 2.8× 0.86 ○ 2.95 考查目的:考查学生因数与积的大小关系掌握情况。 答案:><=< 解析:这四道小题都要根据积和因数的大小关系进行比较。第一小题是7.3乘大于 1 的数,乘得的积比 7.3 大,所以应该填“>”;第二小题是 4.9 乘小于 1 的数,乘得的积比 4.9小,所以应该填“<”; 第三小题是 5.43乘等于 1 的数,乘得的积就是 5.43 ,所以应该填“=”;第四小题是 2.8 乘小于 1 的数,乘得的积比 2.8小,既然比 2.8 小,那就更比 2.95 小,所以应该填“<”。 3.根据运算定律在方框里填上合适的数。 (1) 2.5 ×( 0.77 × 0.4 )=( (2) 6.1 × 3.6 + 3.9 × 3.6 =( ( 3) 2.02 × 8.5 =×8.5+( 4) 48× 0.25 = 0.25 ×××)×+)× ×8.5 考查目的:考查学生对乘法运算定律的掌握情况,以及是否能根据乘法运算定律对算式进行适当的变 换。 答案:( 1)( 2.5 × 0.4 )× 0.77 (2)( 6.1 + 3.9 )× 3.6 (3) 2× 8.5 + 0.02 × 8.5 (4) 0.25 × 4× 12 解析:这四道小题都是根据乘法运算定律对算式进行变换,根据运算定律对算式进行适当的变换是简 便计算的重要基础。解答本题时,首先要看清算式的结构和数据特点,看是否符合运算定律的基本形式? 如果符合,可以直接应用乘法运算定律对算式进行变换;如果不符合,就要思考怎样将算式先变成符合运 算定律的形式?第( 1)小题符合结合律的形式,考虑到数据的特点,可以直接应用乘法交换律、结合律 进行变换。第(2)小题符合乘法分配律的形式,可以直接逆向应用乘法分配律进行变换。第(3)小题是两个数相乘,不符合乘法分配律的形式,但可以将其中一个数“ 2.02 ”改写成“ 2+ 0.02 ”的形式,这样就可以正向应用乘法分配律进行变换。第(4)小题也是两个数相乘,可以将其中一个数“48”改写成“ 4×12”的形式,这样就可以应用乘法交换律、结合律进行变换。 4.在下面算式的括号里填上合适的数。(你能想出不同的填法吗?) 1.26 =()×() =()×()
