B. 1 millimetre____1 centimetre.
C. I hectometre____1 kilometre.
D. 1 decimetre____1 centimetre.

Answer

To fill in the blanks with the appropriate signs (< or >), we need to compare the given units of measurement. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Comparison of Kilometers and Meters:**
- 1 kilometer = 1000 meters
- Therefore, 1 kilometer > 1000 meters.
- **Fill in the blank:** 1 kilometer > 1000 meters

2. **Comparison of Hectometers and Meters:**
- 1 hectometer = 100 meters
- Therefore, 1 hectometer > 100 meters.
- **Fill in the blank:** 1 hectometer > 100 meters

3. **Comparison of Decameters and Meters:**
- 1 decameter = 10 meters
- Therefore, 1 decameter > 10 meters.
- **Fill in the blank:** 1 decameter > 10 meters

4. **Comparison of Meters and Centimeters:**
- 1 meter = 100 centimeters
- Therefore, 1 meter > 100 centimeters.
- **Fill in the blank:** 1 meter > 100 centimeters

5. **Comparison of Meters and Decimeters:**
- 1 meter = 10 decimeters
- Therefore, 1 meter > 10 decimeters.
- **Fill in the blank:** 1 meter > 10 decimeters

6. **Comparison of Decimeters and Centimeters:**
- 1 decimeter = 10 centimeters
- Therefore, 1 decimeter > 10 centimeters.
- **Fill in the blank:** 1 decimeter > 10 centimeters

7. **Comparison of Decameters and Meters:**
- 1 decameter = 10 meters
- Therefore, 1 decameter > 10 meters.
- **Fill in the blank:** 1 decameter > 10 meters

8. **Comparison of Decimeters and Millimeters:**
- 1 centimeter = 10 millimeters
- Therefore, 1 centimeter > 10 millimeters.
- **Fill in the blank:** 1 centimeter > 10 millimeters

9. **Comparison of Hectometers and Kilometers:**
- 1 kilometer = 10 hectometers
- Therefore, 1 kilometer > 10 hectometers.
- **Fill in the blank:** 1 kilometer > 10 hectometers

### Final Filled Blanks:
1. 1 kilometer > 1000 meters
2. 1 hectometer > 100 meters
3. 1 decameter > 10 meters
4. 1 meter > 100 centimeters
5. 1 meter > 10 decimeters
6. 1 decimeter > 10 centimeters
7. 1 decameter > 10 meters
8. 1 centimeter > 10 millimeters
9. 1 kilometer > 10 hectometers
