1、小学数学五年级上小数乘除法练习一班级:姓名:得分:1、直接写出得数。0.45×2.5= 0.8×1.25= 0.3×3.6= 10×0.07= 0.3×1.4= 0.05×7= 27+456+73= 0.3×0.3=7.2+2.8= 0.9÷0.01= 12÷0.3= 2.87÷0.7=13÷4= 0.96÷0.3= 1.5×0.4= 2.5×0.7×0.8= 8-2.5= 16÷1.6= 8×(2.5+0.25)= 0.36+0.64= 64.32÷16= 72.8÷0.8=
2、 8.4÷4.2= 13.8+9.9= 2.4×2.5=0.05×0.8= 2.56-0.37= 1.25×0.8×0.5= 12×2.5= 1.23×3=3.5+3.5×3= 19.6÷2= 8.8÷2.2= (1.5+0.25)×4= 1.6×0.2= 7.2×0.3= 00.5×0.8=8.4×0.2.75×4= 3.2÷1.6= 2.8×0.3= 0.9÷0.15= 1.8×0.4= 5.5÷0.55= 0.08×100=2.2÷0.11= 12.5×0.8= 0.35×0.3=1.4×5= 2
3、、用竖式计算0.396÷1.2= 0.756÷0.36= 15.6×13=0.18×15= 0.025×14= 3.06×36=0.04×0.12= 3.84×2.6≈ 5.76×3= (保留一位小数)7.15×22= 90.75÷3.3 = 3.68×0.25=16.9÷0.13= 1.55÷3.9= 3.7×0.016=13.76×0.8= 5.2×0.6= 8
4、.4×1.3=6.4×0.5= 4.48×0.4= 5.25×5=35.4×4.2 = 0.042×0.54= 0.76×0.32=0.25×0.046 = 2.52×3.4= 1.08×25= 0.12×0.5×0.16= 4.8×0.25= 0.125×1.4≈(保留两位小数)2.5÷0.7= 10.1÷3.3= (保留三位小数)(商用循环小数)10.75÷12.5= 3.25×9.04= (用乘法验算) (用除法验算)3、脱式计算(能简算的
5、要简算)2.5×7.1×416.12×99+16.125.2×0.9+0.97.28×99+7.284.3×50×0.264-2.64×0.526×15.7+15.7×24(2.275+0.625)×0.283.94+34.3×0.22.7×5.4×3.91.2×(9.6÷2.4)÷4.88.9×1.1×4.76.58×4.5×0.93.6×9.85-5.468.05×3.4+7.62.8×0.5+1.584.8-4.8×0.5
