3.99 kilograms = ____milligrams

A.) 3990
B.) 39900
C.) 399000
D.) 3990000

Step 1:
We know that
1 kilogram (kg) = 1000 grams (g)
1 gram (g) = 1000 milligrams (mg)
Step 2:

2.

Fill in the blank to make the conversion true.
4500000 millimeters = ____kilometers

A.) 450
B.) 45
C.) 4.5
D.) 4500

Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 1000 millimeters (mm)
Step 2:
4500000 millimeters = 4500000 mm × 1 m/1000 mm × 1 km/1000 m
= 4.5 km
So, 4500000 millimeters = 4.5 kilometers

3.

Step 1:
We know that
1 kiloliter (kl) = 1000 liters (l)
1 liter (l) = 1000 milliliters (ml)
Step 2:
3356000 milliliters = 3356000 ml × 1 l/1000 ml × 1 kl/1000 l = 3.356 kl
So, 3356000 milliliters = 3.356 kiloliters

4.

Fill in the blank to make the conversion true.
6700000 millimeters = ____kilometers

C.) 67
D.) 6.7

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

5.

Step 2:
2300000 millimeters = 2300000 mm × 1 m/1000 mm × 1 km/1000 m
= 2.3 km
So, 2300000 millimeters = 2.3 kilometers
