小学四年级下册数学小数乘法竖式计算题200道
四年级下册数学乘法竖式例子解析12.8×24
解题思路:先将两乘数末位对齐,然后分别使用第二个乘数,由末位起对每一位数依次乘上一个乘数,最后将所计算结果累加即为乘积,如果乘数为小数可先将其扩大相应的倍数,最后乘积在缩小相应的倍数;
解题过程:
步骤一:4×128=512
步骤二:2×128=2560
根据以上计算步骤组合结果为307.2
验算:307.2÷24=12.8
扩展资料【验算结果】:将被除数从高位起的每一位数进行除数运算,每次计算得到的商保留,余数加下一位数进行运算,依此顺序将被除数所以位数运算完毕,得到的商按顺序组合,余数为最后一次运算结果
解题过程:
步骤一:30÷24=1 余数为:6
步骤二:67÷24=2 余数为:19
步骤三:192÷24=8 余数为:0
根据以上计算步骤组合结果为12.8

小学四年级列竖式计算题大全
小学四年级列竖式计算题如下:
30-(3.8+0.75)
=30-
=30-
=30-(5-0.45)
=30-5+0.45
=25.45
除法
如42除以7。
从4开始除〔从高位到低位〕。除法用竖式计算时,从最高位开始除起,如:42就从最高位十位4开始除起;若除不了,如:4不能除以7,那么就用最高位和下一位合成一个数来除,直到能除以除数为止;如:42除7中4不能除7,就把4和2合成一个数42来除7,商为6。

四年级乘法竖式例子解析83×12
解题思路:先将两乘数末位对齐,然后分别使用第二个乘数,由末位起对每一位数依次乘上一个乘数,最后将所计算结果累加即为乘积,如果乘数为小数可先将其扩大相应的倍数,最后乘积在缩小相应的倍数;
解题过程:
步骤一:2×83=166
步骤二:1×83=830
根据以上计算结果相加为996
验算:996÷12=83
扩展资料~验算结果:将被除数从高位起的每一位数进行除数运算,每次计算得到的商保留,余数加下一位数进行运算,依此顺序将被除数所以位数运算完毕,得到的商按顺序组合,余数为最后一次运算结果
解题过程:
步骤一:99÷12=8 余数为:3
步骤二:36÷12=3 余数为:0
根据以上计算步骤组合结果为83
