一、口算
9.58 - 4.5 =        300×0.09 =        0.8×5 =  
0.6×0.85 =        7.6÷0.02 =        39÷0.39 =  
5.5 - 0.9 =         0.42÷0.6 =        0.19 + 0.1 =  
0.6÷0.03 =        400×2.2 =         7.5÷0.5 =  
0.12×0.3 =        0.1×0.1 =         1.08×10 =  
2.8÷0.5 =         0.21÷7 =         0.48÷0.4 =  
100×0.105 =        0.6×1.3 =         7 - 5.02 =  
12.72÷0.6 =        8.05÷0.05 =       0.96÷1.2 =  
1.5 - 0.44 =        450÷30 =         8.64 - 5.74 =  
7.33 + 0.7 =        200×0.04 =        0.1÷2 =  
答案: 5.08 27 4
0.51 380 100
4.6 0.7 0.29
20 880 15
0.036 0.01 10.8
5.6 0.03 1.2
10.5 0.78 1.98
21.2 161 0.8

#### 二、用短除法求最大公因数

45和15 48和60 20、30和40
答案: 15 12 10
一、口算
0.26×4 =          0.3 + 0.77 =        0.3×0.4÷0.2 =  
54÷36 =          9.82 - 8.2 =        (1 - 0.1)×0.5 =  
0.9 + 1.1 =         1.2×0.8 =         0.9×(2.7 + 0.3) =  
6.3÷21 =          0.39×0.2 =        6.8 - 2.4÷3 =  
5×0.7 =          1.5×4 =          3.6÷(0.9 - 0.6) =  
3.6 - 0.36 =        4.2÷0.3 =         3.6÷1.8÷0.4 =  
0.9 + 2.01 =        5.4×0.5 =         1.25×3.3×8 =  
6.3÷70 =          8×0.125 =         20 - (3.7 + 7.3) =  
2 - 0.6 =          4.9×0.9 =         5×0.75×0.2 =  
3.12×100 =        208÷4 =          2.4 + 0.45 - 1.23 =  
答案: 1.04 1.07 0.6
1.5 1.62 0.45
2 0.96 2.7
0.3 0.078 6
3.5 6 12
3.24 14 5
2.91 2.7 33
0.09 1 9
1.4 4.41 0.75
312 52 1.62
