Answer:
7. 18m = 1800 cm = 18×10² cm
8. 23 dm = 0.23 hm
9. 5 cm = 50 mm
10. 5.3 hL = 530000 mL
11. 167 mm = 0.167 m
12. 1.589 daL = 158.9 dL
13. 35.45 mg = 0.0003545 hg
14. 43 dam = 4300 dm
15. 500 kg = 500000 g
16. 700mL = 0.0007 KL
17. 130 dag = 1.3 kg
18. 59.932 mm = 59.932 × 10 –⁵ km = 59.932 × 10^–5 km
* Note;
1 m —> 100 cm
1 dm —> 0.001 hm
1 cm —> 10 mm
1 hL —> 100000 mL = 10⁵ mL
1mm —> 0.001 m
1 dal —> 100 dL
1 mg —> 0.00001 hg = 10^–5 hg
1 dam—> 100 dm
1 kg —> 1000 g
1 mL —> 0.000001 kL = 10^–6
1 dag —> 0.01 kg
1 mm —> 0.00001 km = 10^–5 km
I hope I helped you^_^
