Question

Observa modele de rezolvare,apoi efectueaza transformarile:
Exemplu: 4 km =? dam Exemplu: 6 000 cm =? dam
4 km = ( 4 x 100 ) dam 6 000 cm = ( 6000 : 1000) dam
4 km = 400 dam 6 000cm = 6 dam


a) 9 hm = ? dm b) 360 dam = ? hm c) 12 dm = ? mm d) 38 000 mm = ? m
17 dam = ? cm 500 dm = ? dam 35 m = ? cm 41 000 dm = ? hm

Answer 1

9hm= 9x1000dm=9000dm
360dam=360:10hm=36 hm

12 dm=12x100mm=1200mm
38000mm:1000=38m
17damx1000=17000cm
500dm:100=5dam
35mx100=3500cm
41000dm:1000=41hm
