# Metric Conversion with Decimal Values: Two-Step Problem Online Quiz

1.

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

A.) 6700
B.) 670
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

2.

Fill in the blank to make the conversion true.
2.8 kilometers = ____millimeters

A.) 2800
B.) 28000
C.) 2800000
D.) 280000

Step 1:
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

A.) 5700
B.) 57000
C.) 570000
D.) 5700000

Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
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

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:
3.99 kilograms = 3.99 kg × 1000 g/1 kg × 1000 mg/1g = 3990000 mm
So, 3.99 kilograms = 3990000 milligrams

5.

Fill in the blank to make the conversion true.
2300000 millimeters = ____kilometers

A.) 23
B.) 2.3
C.) 230
D.) 2300

Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 1000 millimeters (mm)
Step 2:
2300000 millimeters = 2300000 mm × 1 m/1000 mm × 1 km/1000 m
= 2.3 km
So, 2300000 millimeters = 2.3 kilometers

6.

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

7.

Fill in the blank to make the conversion true.
660000 centimeters = ____kilometers

A.) 6600
B.) 660
C.) 66
D.) 6.6

Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 100 centimeters (cm)
Step 2:
660000 centimeters = 660000 cm × 1 m/100 cm × 1 km/1000 m
= 6.6 km
So, 660000 centimeters = 6.6 kilometers

8.

Fill in the blank to make the conversion true.
118000 centimeters = ____kilometers

A.) 1180
B.) 118
C.) 11.8
D.) 1.18

Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 100 centimeters (cm)
Step 2:
118000 centimeters = 118000 cm × 1 m/100 cm × 1 km/1000 m
= 1.18 km
So, 118000 centimeters = 1.18 kilometers

9.

Fill in the blank to make the conversion true.
3356000 milliliters = ____kiloliters

A.) 3.356
B.) 33.56
C.) 335.6
D.) 3356

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

10.

Fill in the blank to make the conversion true.
9.9 kilometers = ____centimeters

A.) 990
B.) 9900
C.) 990000
D.) 99000

Step 1:
We know that
1 kilometer (km) = 1000 meters (m)
1 meter (m) = 100 centimeters (cm)
Step 2:
9.9 kilometers = 9.9 km × 1000 m/1 km × 100 cm/1 m = 990000 cm
So, 9.9 kilometers = 990000 centimeters
