1. 5000 m
1 km = 1000 m. 5 × 1000 = 5000 m.
2. 700 cm
1 m = 100 cm. 7 × 100 = 700 cm.
3. 3000 g
1 kg = 1000 g. 3 × 1000 = 3000 g.
4. 9000 m
1 km = 1000 m. 9 × 1000 = 9000 m.
5. 9900 mL
1 L = 1000 mL. 9.9 × 1000 = 9900 mL.
6. 1500 mL
1 L = 1000 mL. 1.5 × 1000 = 1500 mL.
7. 4300 mL
1 L = 1000 mL. 4.3 × 1000 = 4300 mL.
8. 160 cm
1 m = 100 cm. 1.6 × 100 = 160 cm.
