列竖式计算.
0.37×0.4= | 1.06×25= | 27×0.43= | 0.6×0.39= |
1.7×0.86= | 1.8×2.3= | 2.07×53= | 0.015×2.4= |
3.4×1.6= | 1.08×5.2= | 1.25×3.6= | 3.75×0.24= |
分析:小数乘法的计算法则:按整数乘法的计算法则进行计算,因数里面一共有几位小数,就从积的末尾数出几位点上小数点,据此解答.
解答:解:0.37×0.4=0.148,
1.06×25=26.5,
27×0.43=11.61,
0.6×0.39=0.234,
1.7×0.86=1.462,
1.8×2.3=4.14,
2.07×53=109.71,
0.015×2.4=0.036,
3.4×1.6=5.44,
1.08×5.2=5.616,
1.25×3.6=4.5,
3.75×0.24=0.9.
