Question

多位小数乘除法

Answer 1

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

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=
