Răspuns :

1) 20m + 25cm + 2hm + 0,75m = ?m

20m

25cm = 0,25m

2hm = 200m

0,75m

20m + 0,25m + 200m + 0,75m = 20m + 25cm + 2hm + 0,75hm = 221m

2) 0,0253hm + 5dam + 340cm + 890mm = ?m

0,0253hm = 2,53m

5dam = 50m

340cm = 3,4m

890mm = 0,89m

2,53m + 50m + 3,4m + 0,89m = 0,0253hm + 5dam + 340cm + 890mm = 56,82m
