1. 直接写出得数。
$8.3 + 7.7 =$ $3.5 ÷ 7 =$ $0.56 ÷ 7 =$ $3.689 ÷ 0.32 × 0 =$
$600 × 0.01 =$ $1.7 × 0.5 =$ $7.35 - 5.6 =$ $(8.8 - 3.2) ÷ 7 =$
$3.76 ÷ 10 =$ $8 - 1.93 =$ $10 - 0.87 =$ $6.2 × 101 - 6.2 =$
$4.2 × 5 =$ $1.75 + 2.25 =$ $0.25 × 0.3 =$ $6 × 0.5 ÷ 5 =$
$1.5 - 0.57 =$ $0.12 × 50 =$ $4 × 0.5 =$ $12 ÷ 2.5 ÷ 4 =$
$1.17 × 300 =$ $0.32 ÷ 0.8 =$ $16 - 6.7 =$ $5 - 0.6 × 2 =$
$3.83 - 1.8 =$ $0.14 × 8 =$ $0.16 × 5 =$ $1.5 + 2.26 + 0.5 =$
$4.03 - 0.3 =$ $2.4 ÷ 0.5 =$ $325 - 28.7 =$ $12.5 × 0.24 × 0.8 =$
$3.24 + 0.6 =$ $45 × 0.2 =$ $2.4 ÷ 0.08 =$ $1.8 ÷ 9 × 0.5 =$

2. 用竖式计算。
$9.52 + 21.49 =$         $31 - 11.83 =$         $3.74 × 6.5 =$
$0.48 × 17.2 =$         $26.6 ÷ 3.5 =$         $0.544 ÷ 3.4 =$

答案

1. 计算$9.52 + 21.49$:
竖式计算:
```
9.52
+21.49
------
31.01
```
结果:$9.52 + 21.49 = 31.01$
2. 计算$31−11.83$:
竖式计算:
```
31.00
-11.83
------
19.17
```
结果:$31−11.83 = 19.17$
3. 计算$3.74×6.5$:
竖式计算:
```
3.74
× 6.5
------
1870
2244
------
24.310
```
结果:$3.74×6.5 = 24.31$
4. 计算$0.48×17.2$:
竖式计算:
```
17.2
×0.48
------
1376
688
------
8.256
```
结果:$0.48×17.2 = 8.256$
5. 计算$26.6÷3.5$:
竖式计算:
```
7.6
3.5|26.6
24.5
----
2.10
2.10
----
0
```
结果:$26.6÷3.5 = 7.6$
6. 计算$0.544÷3.4$:
竖式计算:
```
0.16
3.4|0.544
0.34
----
0.204
0.204
----
0
```
结果:$0.544÷3.4 = 0.16$
综上,答案依次为$31.01$;$19.17$;$24.31$;$8.256$;$7.6$;$0.16$。
照下图方式摆$n$个六边形要用$71$根小棒。请你根据题意列方程并求解。
