Answer 1

Salut!

Sa ne amintim!

• 1 m = 10 dm = 100 cm = 1000 mm
• 1 km = 10 hm = 100 dam = 1000 m

a) 5 km = 500 dam ✔

250 m = 25 dam ✔

20 mm = 2 cm ✔

b) 300 000 cm = 30000dm ✔

49 000 cm = 4900 m ✔

537 000 dam = 537 cm ✔

⚫Calculează :

a) 13 km + 400 dm = 1300 dam + 4 dam = 1304 dam ✅

b) 63 hm – 1 300 cm = 6300 m - 13 m = 6287 m✅

c) 16 km x 3 = 48 km = 4800 dam ✅

d) 165 000 cm : 3 = 55000 cm = 55 dam ✅
