Let’s go through each conversion step by step. We’re converting between metric units — like meters to kilometers, grams to kilograms, liters to milliliters, etc.
Remember these key conversions:
- 1 km = 1,000 m → so to go from m to km, divide by 1,000; from km to m, multiply by 1,000
- 1 kg = 1,000 g → same logic: divide by 1,000 to get kg, multiply by 1,000 to get g
- 1 L = 1,000 ml → divide by 1,000 for L, multiply by 1,000 for ml
- 1 cm = 10 mm → divide by 10 for cm, multiply by 10 for mm
Now let’s solve each one:
1a. 2,000 m = ___ km
→ Divide by 1,000 → 2,000 ÷ 1,000 =
2
1b. 9 km = ___ m
→ Multiply by 1,000 → 9 × 1,000 =
9,000
2a. 9,000 ml = ___ L
→ Divide by 1,000 → 9,000 ÷ 1,000 =
9
2b. 3 kg = ___ g
→ Multiply by 1,000 → 3 × 1,000 =
3,000
3a. 6 L = ___ ml
→ Multiply by 1,000 → 6 × 1,000 =
6,000
3b. 90 mm = ___ cm
→ Divide by 10 → 90 ÷ 10 =
9
4a. 6 cm = ___ mm
→ Multiply by 10 → 6 × 10 =
60
4b. 4 km = ___ m
→ Multiply by 1,000 → 4 × 1,000 =
4,000
5a. 1,000 m = ___ km
→ Divide by 1,000 → 1,000 ÷ 1,000 =
1
5b. 2,000 g = ___ kg
→ Divide by 1,000 → 2,000 ÷ 1,000 =
2
6a. 50 mm = ___ cm
→ Divide by 10 → 50 ÷ 10 =
5
6b. 400 cm = ___ m
→ Wait! This is tricky — we need to know how many cm in a meter?
→ 1 m = 100 cm → so divide by 100 → 400 ÷ 100 =
4
7a. 4 L = ___ ml
→ Multiply by 1,000 → 4 × 1,000 =
4,000
7b. 3 km = ___ m
→ Multiply by 1,000 → 3 × 1,000 =
3,000
8a. 10,000 g = ___ kg
→ Divide by 1,000 → 10,000 ÷ 1,000 =
10
8b. 2 cm = ___ mm
→ Multiply by 10 → 2 × 10 =
20
9a. 10,000 m = ___ km
→ Divide by 1,000 → 10,000 ÷ 1,000 =
10
9b. 9,000 g = ___ kg
→ Divide by 1,000 → 9,000 ÷ 1,000 =
9
10a. 4,000 g = ___ kg
→ Divide by 1,000 → 4,000 ÷ 1,000 =
4
10b. 8,000 ml = ___ L
→ Divide by 1,000 → 8,000 ÷ 1,000 =
8
All done! Let me double-check a few random ones to be safe:
- 6 cm to mm → 6×10=60 ✔️
- 400 cm to m → 400÷100=4 ✔️
- 8,000 ml to L → 8 ✔️
Looks good!
