utilizati o singura unitate de masura pentru a exprima: a) 3,15m+23cm+88mm
b) 12,321km+17,679hm+309m
c) 0,01m+0,09dm+0,001km

URGENT ! DAU COROANA !


Răspuns :

a . transformam in mm
3 ,15 m = 3150 mm
23 cm = 230 mm
88 mm
3150 mm + 230 mm + 88 mm= 3468 mm

b. transformam in m
12 ,321 km = 12321 m
17 ,679 hm =1767 , 9 m
0 , 001 km = 1 m
12321 m + 1767 ,9 m + 1m = 14 089 ,9 m

c. transformam in dm
0 ,01m = 0 ,1 dm
0 ,09 dm = 0 ,09 dm
o ,001 km = 10 dm
0 ,1 dm + 0 ,09 dm + 10 dm = 10 ,19 dm
