1、直接写出得数。
0.45×2.5= 0.8×1.25= 0.3×3.6= 0.3×0.3= 10×0.07= 0.3×1.4= 0.05×7= 0.92×0.4= 0.2×0.26= 0.14×4= 0.02×0.1= 1.2×0.3=0.2×0.4= 8.2+1.8= 100-35.22= 2.3×4=
2.5×0.4= 2.4×5= 0.22×4= 3.25×0=
0.9-0.52= 3.99×1= 0×3.52= 12.5×8=
8÷10 = 10-1.8-7.2= 0.43+3.57= 2.5×4×12=
0.9×0.8= 7.5x-3x = a+3a+7a== 1.05×100= 1÷0.5= 0.96÷3= 1.47÷0.7= 5.4÷6=
0.16.5×10= 0.56×100= 3.78×100= 4÷0.8 =
3.215×100= 0.8×10= 4.08×100= 1.1×0.2 =
0.6×0.8 = 3×0.9= 2.5×0.4= 3.6×0.4=
12.5×8= 50×0.04= 80×0.3 = 1.1×9=
0.16×5 = 1.78+2.2 = 9.6÷0.6 = 1.2×0.5-0.4 = 0.7÷0.01 = 2.5×0.4 = 12-3.9= 1.25×8÷1.25 = 6.6÷0.66 = 5.37×0+4.63 = 3.9+2.03= 4.2÷3.5=
1.6+2.4×0.3 = 2.14-0.9= 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= 7÷0.25= 2.5×0.7×0.8= 8-2.5= 16÷1.6= 5.6×1.01= 8×(2.5+0.25)= 0.36+0.64= 64.32÷16= 4.2÷0.1=
72.8÷0.8= 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= 3.2÷1.6= 3.5+3.5×3= 19.6÷2= 8.8÷2.2= 0.75×4= (1.5+0.25)×4= 0.5×0.8=
8.4×0.2= 1.6×0.2= 7.2×0.3= 2.8×0.3= 0.9÷0.15= 1.8×0.4= 5.5÷0.55= 0.08×100=
2.2÷0.11= 5.46+4.54= 12.5×0.8= 0.35×0.3=
1.4×5= 2.8×4= 19.6÷4= 22.5×4=
2、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=

我建议你去买一本《重点难点》或《数学详细解析》石龙购书中心应该有,去看一下吧!
我给你出几道,你做一下:
5*2.5= 8*1.25= 1.26*5.28= 3.5*10.01=
20*5.8= 58*225.2= 15*5.5= 14*25.2=
