北师大版小学数学四年级下册加减乘除计算过关练习题

北师大版小学数学四年级下册加减乘除计算过关练习题

班级:姓名:座号:小数加减法(不进位、不退位)的计算方法:先把各数的小数点对齐(即相同数位对齐),然后从低位算起,还要记得在结果点上小数点。

练习题:一、聪聪家两个月的电费情况如下表。

月份8 9电费52.7元41.2元(1)估一估,两个月的电费100元够吗?说说你的理由。

(2)聪聪家8月份和9月份共付电费多少元?二、三名同学参加百米赛跑。

小张跑了14.55秒,小李比小张跑快了0.24秒,小王比小李慢了0.36秒。

小王跑了多少秒?三、用竖式计算,标Δ的题目要验算。

7.81+2.17=37.68-5.43=Δ12.34+5.6=9.99-5.12= 2.45+36.13=Δ 6.56-4.4=班级:姓名:座号:1.小数进位加法的计算方法:先把小数点对齐(相同数位对齐),然后按整数进位加法的计算方法计算,哪一位上相加的数满十,就向前一位进1,最后在得数里对齐横线上的小数点,点上小数点。

2.小数进位退法的计算方法:先把小数点对齐(相同数位对齐),从低位减起。

如果被减数的小数部分位数不够,可以添“0”再减。

哪一位上的数不够减,要从前一位上退1,在本位上加10再减。

练习题:一、用竖式计算。

3.78+2.6=10-2.76=15.8+3.96=9.18-6.2=二、用2、4、8、0和小数点先组成一个最大的两位小数,再组成一个最小的两位小数,并求出它们的和与差。

三、两个数的差是15.46,被减数减少3.8,减数减少4.65,差变成了多少?四、小丽在计算一道加法题时,把一个加数5.6看成了56,算得的结果是77.9,这道题正确的结果应该是多少?班级:姓名:座号:小数加减混合运算的运算顺序和整数加减混合运算的运算顺序相同,在没有括号的算式里,按从左往右的顺序计算;如果算式里有括号,要先算括号里面的,再算括号外面的。

练习题:一、计算下面各题。

4.2+1.27-3.49 2.3+3.27-4.39 6.42-(2.96+1.04)18.76-5.67+1.2451.69-(11.65-10.1)80-12.4-5.23二、用简便方法计算。
