Let’s solve each problem step by step using the conversion rules:
We know:
- 1 meter (m) = 100 centimeters (cm)
- 1 meter (m) = 1,000 millimeters (mm)
- So, 1 cm = 10 mm (because 100 cm = 1,000 mm → divide both by 100)

Part 1: Convert to the units shown
1.
55 m = ? cm
Multiply by 100: 55 × 100 =
5,500 cm
2.
99 m = ? cm
99 × 100 =
9,900 cm
3.
72 m = ? cm
72 × 100 =
7,200 cm
4.
20 m = ? cm
20 × 100 =
2,000 cm
5.
46 m = ? cm
46 × 100 =
4,600 cm
6.
39 cm = ? mm
Multiply by 10: 39 × 10 =
390 mm
7.
63 m = ? mm
First, convert meters to millimeters: 1 m = 1,000 mm
63 × 1,000 =
63,000 mm
8.
86 m = ? mm
86 × 1,000 =
86,000 mm
9.
44 cm = ? mm
44 × 10 =
440 mm
10.
96 cm = ? mm
96 × 10 =
960 mm

Part 2: Convert to the units shown
Now we’re going from smaller units to bigger ones — so we DIVIDE.
11.
8,000 cm = ? m
Divide by 100: 8,000 ÷ 100 =
80 m
12.
4,000 mm = ? cm
Divide by 10: 4,000 ÷ 10 =
400 cm
13.
2,000 cm = ? m
2,000 ÷ 100 =
20 m
14.
2,000 mm = ? m
Since 1 m = 1,000 mm → divide by 1,000:
2,000 ÷ 1,000 =
2 m
15.
3,000 mm = ? cm
Divide by 10: 3,000 ÷ 10 =
300 cm
16.
7,000 cm = ? m
7,000 ÷ 100 =
70 m
17.
3,000 cm = ? m
3,000 ÷ 100 =
30 m
18.
6,000 mm = ? cm
6,000 ÷ 10 =
600 cm
19.
5,000 cm = ? m
5,000 ÷ 100 =
50 m
20.
1,000 mm = ? cm
1,000 ÷ 10 =
100 cm
