Question

Exprima in metri :
1 mm + 2 cm + 3 dm + 4 m + 5 dm + 6 hm + 7 km =

Answer 1

1 mm = 0.001 m
2 cm = 0.02 m
3 dm = 0.3 m
4m
5 dm(presupun ca trebuia sa fie 5 decametri) = 50m
6 hm = 600m
7 km = 7000m
(+) = 7654,321 m

Answer 2

1mm=0,001 m

2cm=0,02 m

3dm=0,3m
4m=4m
5 dm=0,5 m
6 hm=600 m
7 km=7000 m

0,001+0,02+0,3+4,0+0,5+600+7000=7604,821 m
