Question

Efectueaza operatiile:
12hm-3200cm+730dam= m
130hm+12000m-800dam= km
13000mm+79hm480dm= m
31km+45hm-700m= dam

Answer 1

1) 12 hm-3200 cm+730 dam=… m
1200 m-32 m +7300 m=
1168 m+7300 m= 8468 m
2) 130 hm -1200 m-800 dam=...km
13 km+12 km-8 km=
15 km-8 km=7 km
3) 1300 mm+79 hm-480 dm=… m
13 m+7900 m-48 m=
7913 m-48 m=7865 m
4)31 km+45 hm-700 m= ...dam
3100 dam+450 dam-70 dam=
3550 dam-70 dam=3480 dam
