小数除法竖式必须写成划去小数点的形式嘛?
请教关于五年级小数除法竖式问题:例如6.12÷0.03是把除数转化为整数进行计算,列竖式时候必须写
0.03
)6.12
然后划去小数点0.0)6.1.2的形式嘛?
这样写的时候,有不少学生的小数点“划”的痕迹很不清晰,就像顿号,书写也比较混乱小数除法竖式必须写成划去小数点的形式嘛?
竖式只是求商的手段,竖式不是目的.怎样能方便求商呢?直接列6.12÷3的竖式

请教关于五年级小数除法竖式问题:例如6.12÷0.03是把除数转化为整数进行计算,列竖式时候必须写
0.03
)6.12
然后划去小数点0.0)6.1.2的形式嘛?
这样写的时候,有不少学生的小数点“划”的痕迹很不清晰,就像顿号,书写也比较混乱小数除法竖式必须写成划去小数点的形式嘛?
