Let's work through the conversion problems shown in the image. Here are the given tasks:

1. 3075 mm = ____ m
   To convert millimeters (mm) to meters (m), divide by 1000:
   $3075 \, \text{mm} = \frac{3075}{1000} \, \text{m} = 3.075 \, \text{m}$

2. 87 cm = ____ m
   To convert centimeters (cm) to meters (m), divide by 100:
   $87 \, \text{cm} = \frac{87}{100} \, \text{m} = 0.87 \, \text{m}$

3. 975 cm = ____ mm
   To convert centimeters (cm) to millimeters (mm), multiply by 10:
   $975 \, \text{cm} = 975 \times 10 \, \text{mm} = 9750 \, \text{mm}$

4. 6850 mm = ____ cm
   To convert millimeters (mm) to centimeters (cm), divide by 10:
   $6850 \, \text{mm} = \frac{6850}{10} \, \text{cm} = 685 \, \text{cm}$

5. 48306 m = ____ km
   To convert meters (m) to kilometers (km), divide by 1000:
   $48306 \, \text{m} = \frac{48306}{1000} \, \text{km} = 48.306 \, \text{km}$

Would you like further details on any of these conversions? Here are some related questions for further practice:

1. Convert 5.6 km to meters.
2. Convert 2340 mm to centimeters.
3. Convert 15.75 cm to millimeters.
4. Convert 1.2 m to centimeters.
5. Convert 120000 mm to kilometers.

Tip: Always remember the factor by which you multiply or divide for unit conversions:

• $\text{mm} \leftrightarrow \text{cm} \leftrightarrow \text{m} \leftrightarrow \text{km}$ are all powers of 10!
