2. 0.75×0.8=0.75 \times 0.8 = 

3. 1.2÷0.3=1.2 ÷ 0.3 = 

4. 56−13=\frac{5}{6} - \frac{1}{3} = 

5. 125%×80=125\% \times 80 = 

6. 0.36÷0.09=0.36 ÷ 0.09 = 

7. 25×34=\frac{2}{5} \times \frac{3}{4} = 

8. 1−0.45=1 - 0.45 = 

9. 2.5×40=2.5 \times 40 = 

10. 78÷14=\frac{7}{8} ÷ \frac{1}{4} = 

11. 0.62=0.6^2 = 

12. 310+0.7=\frac{3}{10} + 0.7 = 

13. 48÷1.2=48 ÷ 1.2 = 

14. 49×18=\frac{4}{9} \times 18 = 

15. 0.125×8=0.125 \times 8 = 

16. 512÷56=\frac{5}{12} ÷ \frac{5}{6} = 

17. 3.14×10=3.14 \times 10 = 

18. 75%+0.25=75\% + 0.25 = 

19. 1.5÷0.5=1.5 ÷ 0.5 = 

20. 23×1.5=\frac{2}{3} \times 1.5 = 



二、混合运算(共15题)

直接写出结果:


1. 12×(1+14)=12 \times (1 + \frac{1}{4}) = 

2. 3.6÷0.12−5=3.6 ÷ 0.12 - 5 = 

3. (12+13)×6=(\frac{1}{2} + \frac{1}{3}) \times 6 = 

4. 0.8×25−10=0.8 \times 25 - 10 = 

5. 58÷516+3=\frac{5}{8} ÷ \frac{5}{16} + 3 = 

6. 1.25×0.8÷0.5=1.25 \times 0.8 ÷ 0.5 = 

7. 36×(13−14)=36 \times (\frac{1}{3} - \frac{1}{4}) = 

8. 4.2÷0.7+2.8=4.2 ÷ 0.7 + 2.8 = 

9. 79×18÷2=\frac{7}{9} \times 18 ÷ 2 =
