1、用竖式计算
0.396÷1.2= 0.756÷0.36= 15.6×13=
0.18×15= 0.025×14= 06×36=
0.04×0.12＝ 3.84×2.6≈（保留一位小数） 5.76×23＝
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 8.4×1.3 =
6.4×2.5= 4.48×4.4= 5.25×15 =
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＝ （保留两位小数） 3.25×9.04= （用除法验算）
4.8×0.25＝ 0.125×1.4≈ 10.75÷12.5= （用乘法验算）
2.5÷0.7= （保留三位小数） 10.1÷3.3= （商用循环小数表示）
0.43×0.28= 6.45×0.73= 4.6×0.6=
8.9×0.05= 3.08×0.43= 1.5×26.7=
5.22÷29= 18.72÷3.6= 13.95÷3.1=
2、脱式计算（能简算的要简算）
2.5×7.1×4 = 16.12×99＋16.12= 5.2×0.9＋0.9= 7.28×99+7.28=
4.3×50×0.2= 64－2.64×0.5=2 6×15.7＋15.7×24= (2.275 ＋0.625)×0.28=
3.94+34.3×0.2= 1.2×(9.6÷2.4)÷4.8= 8.9×1.1×4.7= 2.7×5.4×3.9=
3.6×9.85-5.6 = 8.05×3.4+7.6 = 6.58×4.5×0.9= 2.8×0.5+1.58=
4.85 + 0.35 ÷ 1.4= 8.7 × 17.4 - 8.7 × 7.4= (1.25－0.125)×8=
32＋4.9－0.9= 4.8－4.8×0.5 =
4.8×100.1 = 56.5×99＋56.5 = 7.09×10.8－0.8×7.09=
12.5×0.4×2.5×8 = 0.87×3.16+4.64 = 9.5×101=
0.68 ÷（5.2 -3.5）× 1.25= 2．13.×0.×8257=
40.5 ÷ 0.81 × 0.18= 4.8 ×（15 ÷ 2.4）=
6.81+6.81×99= 0.25×185×40= 4.4×0.8－3.4×0.8=
(9.37+9．37+9．37+9．37)× 2．5= 4．2.×1.＋1.×1.75=
2.37×6.3+2.37×3.7= 2.5×1.25×0.32= 3.8×10.1=
2.5×(3.8×0.04=) 7.69×101 = 3.8×10.1 =
0.25×39+0.25= 0.125×72 = 46×0.33+54×0.33=
(8×5.27) ×1.25 = 6.81+6.81×99 = 0.25×185×40=
6.8×0.75÷0.5 = 3.75÷0.125–2.75= 1.53+23.4÷7.2=
9.5×99= 13.5×0.98= 12.5×8.8 =
