Let’s solve each problem step by step.

Part 1: Convert the following

We need to remember metric conversions:

- 1 km = 1000 m → so to go from m to km, divide by 1000
- 1 L = 1000 mL → so to go from mL to L, divide by 1000; from L to mL, multiply by 1000
- 1 cm = 10 mm → so to go from cm to mm, multiply by 10; from mm to cm, divide by 10
- 1 m = 100 cm → so to go from m to cm, multiply by 100; from cm to m, divide by 100
- 1 kg = 1000 g → so to go from g to kg, divide by 1000; from kg to g, multiply by 1000

Now let’s do each one:

① 591 m = ___ km
→ Divide by 1000: 591 ÷ 1000 = 0.591 km

② ___ L = 6720 mL
→ Divide by 1000: 6720 ÷ 1000 = 6.72 L

③ ___ mm = 13.3 cm
→ Multiply by 10: 13.3 × 10 = 133 mm

④ 0.49 m = ___ cm
→ Multiply by 100: 0.49 × 100 = 49 cm

⑤ 2700 g = ___ kg
→ Divide by 1000: 2700 ÷ 1000 = 2.7 kg

⑥ 7.73 km = ___ m
→ Multiply by 1000: 7.73 × 1000 = 7730 m

⑦ ___ m = 923 cm
→ Divide by 100: 923 ÷ 100 = 9.23 m

⑧ 149 mm = ___ cm
→ Divide by 10: 149 ÷ 10 = 14.9 cm

⑨ 27.15 L = ___ mL
→ Multiply by 1000: 27.15 × 1000 = 27150 mL

⑩ ___ g = 3.17 kg
→ Multiply by 1000: 3.17 × 1000 = 3170 g

Part 2: Compare using <, >, or =

We’ll convert both sides to the same unit and compare.

① 1 L vs 960 mL
→ 1 L = 1000 mL → 1000 > 960 → >

② 1000 m vs 1 km
→ 1 km = 1000 m → equal → =

③ 920 m vs 0.85 km
→ 0.85 km = 0.85 × 1000 = 850 m → 920 > 850 → >

④ 1200 g vs 12 kg
→ 12 kg = 12 × 1000 = 12000 g → 1200 < 12000 → <

⑤ 4.5 cm vs 47 mm
→ 4.5 cm = 4.5 × 10 = 45 mm → 45 < 47 → <

⑥ 3.7 m vs 370 cm
→ 3.7 m = 3.7 × 100 = 370 cm → equal → =

⑦ 2.5 L vs 250 mL
→ 2.5 L = 2.5 × 1000 = 2500 mL → 2500 > 250 → >

⑧ 1850 g vs 1.8 kg
→ 1.8 kg = 1.8 × 1000 = 1800 g → 1850 > 1800 → >
