小数乘法计算练习
一、口算。
1.02×0.2=0.45×0.6=0.8×0.125=0.759×0= 0.25×0.4=0.067×0.1=0.1×0.08=0.85×0.4= 8.5+2.5=6.5×3=6.25×7=3200÷8= 8.46×100=2-1.96=5.6-5.56=3.75×4=
二、说一说下面各题的积是几位小数,再用竖式计算。 1.8×23=0.73×0.4=1.06×2.5=0.6×0.39 三、计算下面各题。
0.8×0.9(得数保留一位小数)1.7×0.45(得数保留两位小数) 四、判断,并改错.
10.286×0.32=3.29(保留两位小数)3.27×1.5=4.951.78×0.45≈0.80(保留两位小数)
