Explanation:
Let’s go through each problem step by step, using basic metric conversion facts:
Length conversions:
- 1 m = 100 cm
- 1 cm = 10 mm
- So, 1 m = 1000 mm
- 1 km = 1000 m
Mass conversions:
- 1 kg = 1000 g
Volume conversions:
- 1 L = 1000 mL
Now solve each item:
1) ___ m = 500 cm
→ Since 1 m = 100 cm, divide: 500 ÷ 100 =
5
✔ Answer: 5
2) ___ mL = 8 L
→ 8 × 1000 =
8000
✔ Answer: 8000
3) ___ L = 4000 mL
→ 4000 ÷ 1000 =
4
✔ Answer: 4
4) ___ cm = 80 mm
→ 80 ÷ 10 =
8
✔ Answer: 8
5) 9000 g = ___ kg
→ 9000 ÷ 1000 =
9
✔ Answer: 9
6) ___ m = 700 cm
→ 700 ÷ 100 =
7
✔ Answer: 7
7) ___ mm = 7 cm
→ 7 × 10 =
70
✔ Answer: 70
8) 10 kg = ___ g
→ 10 × 1000 =
10,000
✔ Answer: 10000
9) 10000 g = ___ kg
→ 10000 ÷ 1000 =
10
✔ Answer: 10
10) ___ cm = 30 mm
→ 30 ÷ 10 =
3
✔ Answer: 3
11) ___ m = 800 cm
→ 800 ÷ 100 =
8
✔ Answer: 8
12) 5 kg = ___ g
→ 5 × 1000 =
5000
✔ Answer: 5000
13) ___ cm = 7 m
→ 7 × 100 =
700
✔ Answer: 700
14) ___ kg = 6000 g
→ 6000 ÷ 1000 =
6
✔ Answer: 6
15) ___ m = 500 cm
→ 500 ÷ 100 =
5
✔ Answer: 5
16) 7 m = ___ cm
→ 7 × 100 =
700
✔ Answer: 700
17) 4000 g = ___ kg
→ 4000 ÷ 1000 =
4
✔ Answer: 4
18) ___ m = 500 cm
→ Same as #15 →
5
✔ Answer: 5
19) 30 mm = ___ cm
→ 30 ÷ 10 =
3
✔ Answer: 3
20) 9000 mL = ___ L
→ 9000 ÷ 1000 =
9
✔ Answer: 9
21) 10000 g = ___ kg
→ Same as #9 →
10
✔ Answer: 10
22) 3000 g = ___ kg
→ 3000 ÷ 1000 =
3
✔ Answer: 3
23) 4000 g = ___ kg
→ Same as #17 →
4
✔ Answer: 4
24) ___ g = 8 kg
→ 8 × 1000 =
8000
✔ Answer: 8000
25) ___ mL = 2 L
→ 2 × 1000 =
2000
✔ Answer: 2000
26) 5000 mL = ___ L
→ 5000 ÷ 1000 =
5
✔ Answer: 5
27) 10000 g = ___ kg
→ Again, same as #9 and #21 →
10
✔ Answer: 10
28) ___ m = 300 cm
→ 300 ÷ 100 =
3
✔ Answer: 3
29) ___ kg = 5000 g
→ 5000 ÷ 1000 =
5
✔ Answer: 5
30) ___ m = 6 km
→ 6 × 1000 =
6000
✔ Answer: 6000
Let me double-check a few tricky ones:
- #18 is same as #15 → 5 ✔
- #21, #27 both 10000 g → 10 kg ✔
- #24: 8 kg = 8000 g ✔
- #30: 6 km = 6000 m ✔
All consistent.
