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

a) 9 hm = ? dm
9 hm = (9×1000) dm
9 hm=9000 dm


b) 360 dam = ? hm
360 dam=(360:10) hm
360 dam=36 hm


c) 12 dm = ? mm
12 dm=(12×100) mm
12 dm=1200 mm


d) 38 000 mm = ? m
38 000 mm=(38 000:1000) m
38 000 mm=38 m


17 dam = ? cm
17 dam=(17×1000) cm
17 dam=17 000 cm


500 dm = ? dam
500 dm=(500:100) dam
500 dm=5 dam


35 m = ? cm
35 m=(35×100) cm
35 m=3500 cm


41 000 dm = ? hm
41 000 dm=(41 000:1000) hm
41 000 dm=41 hm
