乘法:0.9×3.99 3.14×0.9 6.87×2.4 7.98×2.17 9.9×7.4 2.99×0.7 0.1×0.1 2.33×17.3
2.9×0.36 1.24×78.1 0.17×7.8 9.47×0.1 15.7×6.28 0.99×7.4 3.14×9.1 1.9×2.9 8.4×2.3 6.3×8.22 7.88×2.004 2.8×6.3
除法:0.1÷0.1 0.3÷0.9 0.7÷0.1 17.4÷0.3 0.81÷0.9 0.17÷7.8 28.26÷3.14 2.1÷0.7
9.99÷1.11 0.2÷0.4 3.14÷0.2 2.5÷0.5 0.02÷24 113.04÷3.6 2.73÷2.1 72.24÷8.6
37.5÷12.5 2.9÷0.3 72.7÷0.6 28.26÷15.7
0.4/0.2
0.7/0.35
1.98/9.9
7.48/2.5
8/0.25
176/0.011
220/6.6
98.4/0.16
84.3/0.05
100/2.5
3.4/0.17
7.4/370
589/62.5
59.35/87.5
300.54/0.0375
4.56/0.912
8.88/1.28
3.54/17.7
0.0043/62.5
62.5/37.5
然后把除号改成乘号做一遍。就是小数乘法
