十道小数乘与小数的题和十道小数除小数的题

小数乘以小数：
31.5×24.5 =
0.8×0.56 =
4.23×0.028 =
0.63×1.05 =
4.6×25 =
0.41×56 =
1.085×305 =
0.076×24 =

7.34×4.5 =
0.24×0.25=
4.3×0.015=
0.067×0.53=

小数除以小数：
8.63÷0.42 =
0.38×2.6=
1.24÷1.5=
0.56÷0.045 =
2.3÷5.5=
8.63÷0.42 =
28÷0.63=
0.094÷0.12=
3.04÷7.5=
6.32÷2.1 =
3.65÷2.5=
24.36÷1.2=

5.98÷0.23=
19.76÷5.2 =

混合计算：
0.125×0.25×8×4=
7.4×0.28+0.28×2.6=
4.8×0.9+0.48 =
（4－0.4）×2.5 =
2.5 ×（ 0.77 × 0.4）=
6.1×3.6＋3.9×3.6 =
（4+0.4）×2.5=
8×7×0.125=
10－2.3×1.2 =
3.9×9.9+0.39　=
4.5×1.2＋2.3=
（0.4+1.25）×0.8=
9.4×6.1×2.3 =
3.25×4.76－7.8 =
18.1×0.92＋3.93=
1.5×1.3×4 =
2.7＋3.1＋2.9＋3.2 =
1.2×2.5＋0.8×2.5 =
0.78×101 =
25÷0.25×6 =
68.04÷（0.21×3.6）=
0.486＋0.01＋3.99=
19.75÷2.5-3.55=
1.25×11×4×0.8=
17.5×2.3-7.5×2.3=
90÷25÷4 =
8.93×5.7＋8.93×3.3＋8.93=

若除法中有除不尽的可以保留两位小数。

你没计算机啊

有很多啊，你去书店买本练习来做。或者在教材里面找。
