一、直接写出结果。

0.8+0.6= 1.25×80= 5.24+3.76= 625×0.8= 4.2-3.6= 0.32÷16=13+0.26=

9.6÷16= 14.5-0.24= 4÷8= 1.3+8.46= 0.8-0.45= 5×2.4= 1-0.01= 8.1÷3=

2.4÷12= 250×0.4= 20.5+2.05= 37.5×400= 0.78+2.2= 1.5×8= 6×1.5=

25×0.4= 9.6÷16= 4-0.04= 4.15+0.85= 10-0.1= 0.13×7= 9.6÷4= 0.16÷8=

二、列竖式计算

1.64+2.35= 8.65-6.31= 28.448÷14= 0.58×250= 12.5+3.6=

10.88÷34= 10-7.64= 1.86×7= 13.88-6.29= 926×0.15=

8÷500= 26.3+7.93= 23×7.06= 100.2-2.28= 44÷9(精确到百分位)

三、计算(能简便的用简便方法计算)

8×25×1.25×16 4.04×250 45.55-(6.82+15.55)

3.2×99+3.2 4.8×39+61×4.8 34.52-17.87-12.23

2.5×56+4.5×65 489×101-489 4.57+3.17+3.43+5.83

(85+40)×(20-5) 578-405÷45×16 4.6×56+48×4.6-4.6×4

1. 3/7 × 49/9 - 4/3
2. 8/9 × 15/36 + 1/27
3. 12× 5/6 – 2/9 ×3
4. 8× 5/4 + 1/4
5. 6÷ 3/8 – 3/8 ÷6
6. 4/7 × 5/9 + 3/7 × 5/9
7. 5/2 -( 3/2 + 4/5 )
8. 7/8 + ( 1/8 + 1/9 )
9. 9 × 5/6 + 5/6
10. 3/4 × 8/9 - 1/3
11. 7 × 5/49 + 3/14
12. 6 ×( 1/2 + 2/3 )
13. 8 × 4/5 + 8 × 11/5
14. 31 × 5/6 – 5/6
15. 9/7 - ( 2/7 – 10/21 )
16. 5/9 × 18 – 14 × 2/7
17. 4/5 × 25/16 + 2/3 × 3/4
18. 14 × 8/7 – 5/6 × 12/15
19. 17/32 – 3/4 × 9/24
20. 3 × 2/9 + 1/3
21. 5/7 × 3/25 + 3/7
22. 3/14 ×× 2/3 + 1/6
23. 1/5 × 2/3 + 5/6
24. 9/22 + 1/11 ÷ 1/2
25. 5/3 × 11/5 + 4/3
26. 45 × 2/3 + 1/3 × 15
27. 7/19 + 12/19 × 5/6
28. 1/4 + 3/4 ÷ 2/3
29. 8/7 × 21/16 + 1/2
30. 101 × 1/5 – 1/5 × 21
偶也是偶尔看到地,凑合凑合吧
