Question

1) 12 Km = _________ dm
2) 23 mm = __________ hm
3) 486 cm = __________ mm
4) 4 km = ___________ dam
5) 138 dm = _____ hm​

Answer 1

Respuesta:

$12 km (\frac{10000 dm}{1 km } )= 120000 dm\\\\23 mm (\frac{1 m}{1000 mm} )(\frac{1 hm}{100 m} )=2.3x10^{-4} hm\\\\486 cm (\frac{10 mm}{1 cm} )= 4860 mm\\\\4 km (\frac{1000 m}{1 km} )(\frac{1 dam}{10m} )=400 dam\\\\138 dm (\frac{1 hm}{1000 dm} )= 0.138 hm$
