Question

mai intai exprima in aceeasi unitate de masura apoi calculeaza 
7m+200dm+3200cm=...m

15cm+200mm+13m=...cm
150dam+15 km+7hm=...dam
2dm+1hm+7m=...cm

Answer 1

7m + 200dm + 3200cm = m
200dm = 2000m
3200cm = 32 m
7m + 200m+32m= 239 m

15cm + 200mm + 13m = cm
 200mm = 20 cm
13 m = 1300 cm
 15 cm + 20 cm + 1300 cm = 1335 cm

150 dam + 15m +7hm = dam
15 m = 0,0015 dam
7 hm = 70 dam
150 dam + 0,0015 dam + 70 dam = 220,15 dam

2dm + 1hm + 7cm = cm
2 dm = 20 cm
1 hm = 100000 cm
20 cm + 100000cm + 7cm = 100027 cm
