Problem Description:
The task involves arranging numbers in
ascending order (smallest to largest) and
descending order (largest to smallest). The numbers are provided, and the solution should be written in the boxes next to the train cars.
Solution:
####
Part A: Arrange the numbers in ascending order
1.
Numbers given: 115, 98, 78
- To arrange these numbers in ascending order, we compare them and list them from smallest to largest.
- Comparison:
- 78 is the smallest.
- 98 is larger than 78 but smaller than 115.
- 115 is the largest.
- Ascending order:
78, 98, 115
Answer for Question 1:
```
78 → 98 → 115
```
2.
Numbers given: 652, 89, 174, 128, 528
- To arrange these numbers in ascending order, we compare them and list them from smallest to largest.
- Comparison:
- 89 is the smallest.
- 128 is larger than 89 but smaller than 174.
- 174 is larger than 128 but smaller than 528.
- 528 is larger than 174 but smaller than 652.
- 652 is the largest.
- Ascending order:
89, 128, 174, 528, 652
Answer for Question 2:
```
89 → 128 → 174 → 528 → 652
```
####
Part B: Arrange the numbers in descending order
3.
Numbers given: 76, 54, 162
- To arrange these numbers in descending order, we compare them and list them from largest to smallest.
- Comparison:
- 162 is the largest.
- 76 is larger than 54 but smaller than 162.
- 54 is the smallest.
- Descending order:
162, 76, 54
Answer for Question 3:
```
162 → 76 → 54
```
4.
Numbers given: 938, 452, 306, 108
- To arrange these numbers in descending order, we compare them and list them from largest to smallest.
- Comparison:
- 938 is the largest.
- 452 is larger than 306 and 108 but smaller than 938.
- 306 is larger than 108 but smaller than 452.
- 108 is the smallest.
- Descending order:
938, 452, 306, 108
Answer for Question 4:
```
938 → 452 → 306 → 108
```
Final Answers:
1.
Ascending order: 78, 98, 115
2.
Ascending order: 89, 128, 174, 528, 652
3.
Descending order: 162, 76, 54
4.
Descending order: 938, 452, 306, 108
Boxed Final Answer:
\[
\boxed{
\begin{array}{l}
\text{1. } 78 \rightarrow 98 \rightarrow 115 \\
\text{2. } 89 \rightarrow 128 \rightarrow 174 \rightarrow 528 \rightarrow 652 \\
\text{3. } 162 \rightarrow 76 \rightarrow 54 \\
\text{4. } 938 \rightarrow 452 \rightarrow 306 \rightarrow 108
\end{array}
}
