1. 2000 g = ______ mg
2. 104 m = ______ km
3. 48.0 m = ______ cm
4. 6 da = ______ m
5. 1.26 hm = ______ km
6. 20 g = ______ mg
7. 104 l = ______ ml
8. 480 cm = ______ mm
9. 6 l = ______ ml
10. 27 hm = ______ km
11. 78 mg
12. 7.5 km
13. 650 cm
14. 12 da
15. 5.2 hm
16. 50 mg
17. 9.4 km
18. 4.5 cm
19. 4 da

Explanation:

Step1: Recall conversion factors

1 g = 1000 mg, 1 km = 1000 m, 1 m = 100 cm, 1 m = 10 dm, 1 km = 10 hm, 1 L = 1000 mL, 1 cm = 10 mm.

Step2: Solve 35

2000 g = 2000×1000 mg = 2000000 mg.

Step3: Solve 36

104 m = 104÷1000 km = 0.104 km.

Step4: Solve 37

48.0 m = 48.0×100 cm = 4800 cm.

Step5: Solve 38

6 da (decameters) = 6×10 m = 60 m.

Step6: Solve 39

1.26 hm = 1.26÷10 km = 0.126 km.

Step7: Solve 40

20 g = 20×1000 mg = 20000 mg.

Step8: Solve 41

104 L = 104×1000 mL = 104000 mL.

Step9: Solve 42

480 cm = 480×10 mm = 4800 mm.

Step10: Solve 43

6 L = 6×1000 mL = 6000 mL.

Step11: Solve 44

27 hm = 27÷10 km = 2.7 km.
