Question

Observa modelele de rezolvare, apoi efectuează transformările:
4 km /?/ dam
4 km = (4 x 100) dam
4 km = 400 dam
6 000 cm ?| dam
6 000 cm = (6 000: 1 000) dam
6 000 cm = 6 dam
a. 9 hm = ? dm
17 dam =?cm
b. 360 dam = ? hm
500 dm = ? dam
c. 12 dm = ?)mm
=?cm
35 m =
d. 38 000 mm = ?m
41 000 dm = ? hm​
Dacă puteți să le rezolvați pe toate

Answer 1

9hm= ?dm

9hm=(9× 1000)dm

9hm=9000dm

17dam=?cm

17dam=(17×1000)cm

17dam=17000cm

360dam=?hm

360dam=(360:10)

360dam=36hm

500dm=?dam

500dm=(500:100)

500dm=5da.

12dm=?mm

12dm=(12×100)mm

12dm=1200mm

38000mm=?m

38000mm=(38000: 1000)m

38000mm=38m

41000dm=?hm

41000dm=(41000: 1000)hm

41000dm=41hm
