五年级小数除法竖式题演示78.1÷0.32
解题思路: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:因为除数不为整数,首先将除数化为整数为32,被除数同时扩大同样的倍数为:7810
步骤二:78÷32=2 余数为:14
步骤三:141÷32=4 余数为:13
步骤四:130÷32=4 余数为:2
根据以上计算计算步骤组合结果商为244、余数为0.02
验算:244×0.32+0.02=78.1
扩展资料←验算结果:四则运算规则(按顺序计算,先算乘除后算加减,有括号先算括号,有乘方先算乘方)即脱式运算(递等式计算)需在该原则前提下进行
解题过程:
244×0.32+0.02
=78.08+0.02
=78.1
