六年级数学小数乘除法计算题一、小数乘法计算题（10题）1. 0.5×0.3 =- 解析：计算小数乘法时，先按照整数乘法的方法计算，5×3 = 15。

然后看因数中一共有两位小数，就从积的右边起数出两位点上小数点，所以0.5×0.3 = 0.15。

2. 1.2×0.4 =- 解析：先算12×4 = 48，因数共有两位小数，从积的右边起数出两位点上小数点，结果是0.48。

3. 0.6×0.8 =- 解析：按照整数乘法计算6×8 = 48，因数中共有两位小数，所以积为0.48。

4. 2.5×0.2 =- 解析：计算25×2 = 50，因数共有两位小数，积是0.5。

5. 1.5×0.3 =- 解析：15×3 = 45，因数有两位小数，结果为0.45。

6. 0.7×0.9 =- 解析：7×9 = 63，因数共两位小数，积是0.63。

7. 3.2×0.5 =- 解析：32×5 = 160，因数有一位小数，积是1.6。

8. 0.4×1.5 =- 解析：4×15 = 60，因数共有两位小数，积是0.6。

- 解析：21×4 = 84，因数有两位小数，积为0.84。

10. 1.8×0.5 =- 解析：18×5 = 90，因数有一位小数，积是0.9。

二、小数除法计算题（10题）1. 0.6÷0.3 =- 解析：根据小数除法的计算方法，将被除数和除数同时扩大10倍，变成6÷3 = 2。

2. 1.2÷0.4 =- 解析：把被除数和除数同时扩大10倍，变为12÷4 = 3。

3. 0.8÷0.2 =- 解析：被除数和除数同时扩大10倍，得到8÷2 = 4。
