北师大版四年级下册数学计算题
北师大版四年级下册数学计算题一、小数加减法1. 计算:3.56 +2.44解析:小数加法计算时,要将小数点对齐,也就是相同数位对齐。
然后按照整数加法的方法进行计算。
3.56的个位是3,十分位是5,百分位是6;2.44的个位是2,十分位是4,百分位是4。
先计算百分位6 + 4 = 10,满十向十分位进1,百分位写0;再计算十分位5+4 + 1(进位)=10,满十向个位进1,十分位写0;最后计算个位3+2+1(进位) = 6。
所以结果是6。
2. 计算:5.63.28解析:小数减法同样要将小数点对齐。
5.6的个位是5,十分位是6;3.28的个位是3,十分位是2,百分位是8。
先从百分位减起,因为6没有百分位,可看作6.00,0 8不够减,从十分位借1当10,10 8 = 2;十分位6被借走1剩5,5-2 = 3;个位5 3 = 2。
所以结果是2.32。
二、小数乘法1. 计算:2.5×3.6解析:按照整数乘法计算25×36 = 900。
2.5是一位小数,3.6是一位小数,总共两位小数,从积900的右边起数出两位点上小数点,结果是9.00,小数末尾的0可以去掉,所以最终结果是9。
2. 计算:0.48×0.25解析:先算48×25 = 1200。
0.48是两位小数,0.25是两位小数,一共四位小数,从1200右边起数出四位点上小数点,结果是0.12。
三、小数除法1. 计算:7.5÷2.5解析:除数是小数的除法,先将除数2.5转化为整数,根据商不变的性质,除数扩大10倍变为25,被除数7.5也要扩大10倍变为75。
然后计算75÷25 = 3。
2. 计算:1.26÷0.28解析:把0.28扩大100倍变成28,1.26也要扩大100倍变成126。
126÷28 = 4.5。
四、四则混合运算1. 计算:3.6×(2.5 + 1.5)解析:先算括号里的2.5+1.5 = 4,再算3.6×4 = 14.4。
