75 cm [] 75 mm
400 km[] 40 000 hm
48 hm [] 4 800 dm

3x120m [] 4x97 dm
12m + 24 cm [] 10 m +28 cm
69 cm : 3 [] 20 cm +33mm
16 dm x4 [] 1 280dm :10 .
DAU COROANA , va rog!

Answer 1

3 m = 30 dm ; deoarece m > dm de 10 ori

75 cm > 75 mm

75 cm = 750 mm

400 km < 40 000 hm

400 km = 4 000 hm

40 000 hm : 10 = 4 000 km

48 hm > 4 800 dm

48 hm = 48 000 dm

48 000 dm > 4 800 dm

____________________

3 x 120 m > 4 x 97 dm

360 m = 3 600 dm

4 x 97 dm = 388 dm

3 600 dm > 388 dm

___________________

12 m + 24 cm > 10 m +28 cm

1 200 cm + 24 cm = 1 224 cm

1 000 cm + 28 cm = 1 028 cm

1 224 cm > 1 028 cm

____________________

69 cm : 3 < 20 cm +33 mm

23 cm = 230 mm

20 cm = 200 mm

200 mm + 33 mm = 233 mm

230 mm < 233 mm

16 dm x 4 < 1 280 dm : 10

64 dm < 128 dm
