246dm = .....m .....dm
5hg 68g = .....g
5500g = ....kg
2070kg = .....tấn ........kg
640 tạ = ......kg
16dam2 10m2 = .....m2
37dam2 9m2 = .......m2
21mm2 = .........m2
7km2 5hm2 = ....dam2
2m2 12cm2 = .......cm2
34 dm2 = .....m2

Answer 1

36dm = \(\dfrac{18}{5}\)m

246dm = 24m 6dm

5hg 68g = 568g

2070kg = 64000kg

16dam² 10m² = 1610m²

37dam² 9m² = 379m²

21mm² = \(\dfrac{21}{1000000}\)m²

7km² 5hm² = 70500dam²

2m² 12cm² = 20012cm²

34dm² = \(\dfrac{17}{50}\)m²

Answer 2

36dm = 211000000211000000m²

7km² 5hm² = 70500dam²

2m² 12cm² = 20012cm²

34dm² =
