To help solve the exercise in your image, I'll walk you through each part:

### Exercise 7E

1. **Rewrite in descending order:**
   - a. \( 8.04 \quad 8.059 \quad 8.46 \quad 8.63 \quad 8.06 \quad 8.02 \)
     - **Descending Order:** \( 8.63, 8.46, 8.059, 8.06, 8.04, 8.02 \)
   - b. \( 8.52 \quad 8.65 \quad 8.01 \quad 8.14 \quad 8.96 \quad 8.02 \)
     - **Descending Order:** \( 8.96, 8.65, 8.52, 8.14, 8.02, 8.01 \)
   - c. \( 6.39 \quad 6.43 \quad 6.45 \quad 6.80 \quad 3.91 \quad 3.48 \)
     - **Descending Order:** \( 6.80, 6.45, 6.43, 6.39, 3.91, 3.48 \)
   - d. \( 4.86 \quad 4.05 \quad 4.06 \quad 8.30 \quad 3.91 \quad 3.48 \)
     - **Descending Order:** \( 8.30, 4.86, 4.06, 4.05, 3.91, 3.48 \)
   - e. \( 6.36 \quad 6.39 \quad 6.30 \quad 3.91 \quad 5.86 \quad 5.87 \)
     - **Descending Order:** \( 6.39, 6.36, 6.30, 5.87, 5.86, 3.91 \)
   - f. \( 8.52 \quad 8.59 \quad 8.19 \quad 8.46 \quad 8.65 \quad 8.96 \)
     - **Descending Order:** \( 8.96, 8.65, 8.59, 8.52, 8.46, 8.19 \)

2. **Rewrite in ascending order:**
   - a. \( 10.04 \quad 19.04 \quad 19.06 \quad 19.01 \quad 20.14 \quad 19.9 \)
     - **Ascending Order:** \( 10.04, 19.01, 19.04, 19.06, 19.9, 20.14 \)
   - b. \( 7.61 \quad 7.94 \quad 7.62 \quad 7.6 \quad 7.1 \quad 7.02 \)
     - **Ascending Order:** \( 7.02, 7.1, 7.6, 7.61, 7.62, 7.94 \)
   - c. \( 9.09 \quad 8.52 \quad 9.01 \quad 8.09 \quad 9.23 \quad 9.16 \)
     - **Ascending Order:** \( 8.09, 8.52, 9.01, 9.09, 9.16, 9.23 \)
   - d. \( 7.23 \quad 7.62 \quad 7.9 \quad 9.72 \quad 9.61 \quad 9.16 \)
     - **Ascending Order:** \( 7.23, 7.62, 7.9, 9.16, 9.61, 9.72 \)

3. **Challenge:**
   - Using the digits \(7, 8, 2\) with a decimal point:
     - **Biggest number less than 1:** \(0.872\)
     - **Biggest number between 7 and 8:** \(7.82\)

4. **Application in real life (Quiz result question):**
   - In a quiz competition, Team A secured 84.5 points and Team B secured 85 points. Team B won the quiz because they had the higher score.

5. **100 m race timings:**
   - The 100 m race timings are:  
     - Rohan: \(20.52 \, \text{seconds}\)
     - Ananth: \(20.25 \, \text{seconds}\)
     - Suraj: \(20.05 \, \text{seconds}\)
     - Prashant: \(20.05 \, \text{seconds}\)
   
   **Who came first?**  
   Since Suraj and Prashant have the lowest time (\(20.05\) seconds), they came first. The order is:
   - Suraj/Prashant
   - Ananth
   - Rohan

Would you like more details on any of these solutions or have any questions?

Here are 5 additional questions for you to explore:
1. What is the smallest number you can form using the digits 7, 8, and 2 with a decimal point?
2. What is the time difference between the first and last place in the 100 m race?
3. If Team A had scored 86 points instead of 84.5, which team would have won?
4. How many unique three-digit numbers can you form using 7, 8, and 2?
5. Can you write the descending order of the 100 m race times including decimal precision?

**Tip:** Always ensure to line up decimal points correctly when comparing numbers!

Solve the following exercises: 1. Rewrite in descending and ascending order, 2. Solve a challenge using digits, 3. Analyze race timings.

Learn how to order decimal numbers in ascending and descending order, solve challenges using digits with decimal points, and analyze race timings based on the smallest time. Suitable for students in Grades 4-6.
