四年级下册数学小数点乘法计算题
四年级下册数学小数点乘法计算题
一、基础计算类
1. 0.3×0.5 =
解析：计算小数乘法时，先按照整数乘法的方法计算，3×5 = 15。
然后看因数中一共有几位小数，0.3和0.5一共有两位小数，就从积的右边起数出两位点上小数点，所以结果是0.15。
2. 1.2×0.4 =
解析：先算12×4 = 48，因数1.2有一位小数，0.4也有一位小数，共两位小数，从积的右边起数出两位点上小数点，得到0.48。
3. 2.5×0.8 =
解析：计算25×8 = 200，因数2.5有一位小数，0.8有一位小数，总共两位小数，那么结果是2.00，小数末尾的0可以去掉，结果为2。
二、整十数与小数相乘类
1. 0.6×30 =
解析：可以先算6×30 = 180，0.6有一位小数，从积的右边起数出一位点上小数点，结果是18.0，也就是18。
2. 20×0.15 =
解析：先算20×15 = 300，因数0.15有两位小数，从积的右边起数出两位点上小数点，得到3.00即3。
三、小数连乘类
1. 0.2×0.3×0.4 =
解析：按照从左到右的顺序计算。
先算0.2×0.3 = 0.06，再算0.06×0.4 = 0.024。
2. 1.5×0.2×0.5 =
解析：先计算1.5×0.2 = 0.3，然后0.3×0.5 = 0.15。
