Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 1000 millimeters (mm)
Step 2:
6700000 millimeters = 6700000 mm × 1 m/1000 mm × 1 km/1000 m
= 6.7 km
So, 6700000 millimeters = 6.7 kilometers

  • 2. Fill in the blank to make the conversion true.

We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 1000 millimeters (mm)
Step 2:
2.8 kilometers = 2.8 km × 1000 m/1 km × 1000 mm/1m = 2800000 mm
So, 2.8 kilometers = 2800000 millimeters

  • 3. Fill in the blank to make the conversion true.
    5.7 kilometers = ____millimeters

Answer: Option 'D'

Step 1:
We know that

1 meter (m) = 1000 millimeters (mm)
Step 2:
5.7 kilometers = 5.7 km × 1000 m/1 km × 1000 mm/1m = 5700000 mm
So, 5.7 kilometers = 5700000 millimeters

  • 4. Fill in the blank to make the conversion true.
    3.99 kilograms = ____milligrams

Answer: Option 'D'
