小数的乘除法计算题
20 道小数乘除法计算题一、小数乘法1. 2.5×3.6-解析:先按照整数乘法计算,25×36 = 900。
然后看因数中一共有两位小数,从积的右边起数出两位点上小数点,结果是9。
2. 1.2×4.5-解析:12×45 = 540,因数中一共有两位小数,结果是5.4。
3. 0.8×0.7-解析:8×7 = 56,因数中一共有两位小数,结果是0.56。
4. 3.2×2.1-解析:32×21 = 672,因数中一共有两位小数,结果是6.72。
5. 4.5×1.8-解析:45×18 = 810,因数中一共有两位小数,结果是8.1。
二、小数除法6. 12.6÷3-解析:126÷3 = 42,被除数和除数同时扩大10 倍,商不变。
所以12.6÷3 = 4.2。
7. 25.2÷6-解析:252÷6 = 42,被除数和除数同时扩大10 倍,商不变。
所以25.2÷6 = 4.2。
8. 18.9÷3-解析:189÷3 = 63,被除数和除数同时扩大10 倍,商不变。
所以18.9÷3 = 6.3。
9. 36.4÷8-解析:364÷8 = 45.5,被除数和除数同时扩大10 倍,商不变。
所以36.4÷8 = 4.55。
10. 42.5÷5-解析:425÷5 = 85,被除数和除数同时扩大10 倍,商不变。
所以42.5÷5 = 8.5。
11. 15.6÷4-解析:156÷4 = 39,被除数和除数同时扩大10 倍,商不变。
所以15.6÷4 = 3.9。
12. 21.7÷7-解析:217÷7 = 31,被除数和除数同时扩大10 倍,商不变。
