题目内容
【题目】直接写得数.
+= += ﹣= 10﹣4.8﹣3.2=
1﹣= 0.5×0.2÷0.5×0.2= 1﹣﹣= ﹣=
0.125×0.25×32= 7﹣6.38= += 3.9+6.1﹣3.9+6.1=
【答案】,,,2,,0.04,,,1,0.62,,12.2
【解析】
试题分析:根据分数和小数加减乘除的计算方法进行计算即可;0.5×0.2÷0.5×0.2按照从左向右的顺序计算;0.125×0.25×32,把32拆成8×4,根据乘法交换律和结合律进行计算.
解:+=, +=, ﹣=, 10﹣4.8﹣3.2=2,
1﹣=, 0.5×0.2÷0.5×0.2=0.04, 1﹣﹣=, ﹣=,
0.125×0.25×32=1, 7﹣6.38=0.62, +=, 3.9+6.1﹣3.9+6.1=12.2.
