期中典例专练一：小数乘除法列竖式计算--五年级数学上册(解析版)人教版
2023-2024学年五年级数学上册期中典例专练一：小数乘除法列竖式计算1列竖式计算。
2.36×0.22= 16.415÷6.7=0.091÷0.75≈(得数保留两位小数) 2.75×4.08=【答案】0.5192；2.450.12；11.22【分析】小数乘小数的计算方法，先按照整数乘法的计算方法计算，再看因数中共有几位小数，就从积的右边起数出几位点上小数点；小数除法计算方法：在计算除数是小数的除法时。
根据商不变的性质，将除数和被除数同时扩大相同的倍数，转化成除数是整数的除法进行计算；得数保留两位小数，看千分位上的数字是否满5，然后运用“四舍五入”法求得近似数即可。
【详解】2.36×0.22=0.5192 16.415÷6.7=2.450.091÷0.75≈0.12 2.75×4.08=11.222列竖式计算。
21×1.7= 5.23×1.2=161÷0.47≈(得数保留两位小数) 5.39×0.78≈(得数保留三位小数)【答案】35.7；6.276342.55；4.204【分析】小数乘法法则：先按照整数乘法的计算法则算出积，再看因数中共有几位小数，就从积的右边起数出几位，点上小数点；如果位数不够，就用“0”补足；除数是小数的除法计算法则：先移动除数的小数点，使它变成整数，被除数的小数点也向右移动几位(位数不够的补“0”)，然后按照除数是整数的除法法则进行计算；保留几位小数，就看保留小数的下一位小数，再根据“四舍五入”法进行解答。
【详解】21×1.7=35.7 5.23×1.2=6.276161÷0.47≈342.55 5.39×0.78≈4.2043列竖式计算。
7.51×4.3≈(得数保留一位小数) 4.08×25=0.29×4.3= 25.6÷4=【答案】32.3；1021.247；6.4【分析】小数乘小数的计算方法，先按照整数乘法的计算方法计算，再看因数中共有几位小数，就从积的右边起数出几位点上小数点；得数保留一位小数，看百分位上的数字是否满5，然后运用“四舍五入”法求得近似数即可；根据除数是整数的小数除法的运算法则，除数是整数的小数除法，按照整数除法的法则去除，商的小数点要和被除数的小数点对齐；如果除到被除数的末尾仍有余数，就在余数后面添0再继续除，据此计算。
