这样的脱式计算题很多,10道题如下:
5.3×6.3+2.3,4.4×7.3+5.3 ,4×8.8+1.5, 4.1×0.8-0.2 ,9.9×1.4+0.6, 6.4×2.4+3.6 ,
12.48-4×9.7 ,9.8×1.3-0.8,
4.4×7.3+5.3 ,4×8.8+1.5
1. 0.5 + 0.3 = 0.8
2. 2.5 - 1.7 = 0.8
3. 0.4 × 0.5 = 0.2
4. 3.6 ÷ 2 = 1.8
5. 0.7 × 0.6 = 0.42
6. 4.8 ÷ 0.2 = 24
7. 0.9 + 0.02 = 0.92
8. 1.5 - 0.7 = 0.8
9. 0.3 × 0.4 = 0.12
10. 2.4 ÷ 0.6 = 4。
