Answer 1

a) 4k = 4 000m

4km + 3 500m = 4 000m + 3 500m = 7 500m

b) 0,09hm = 9m; 0,5dam = 0,5m

0,09hm + 0,05dam = 9m + 0,5m = 9,5m

c) 1 200mm = 1,2m; 340cm = 3,4m

1 200mm + 340cm + 3m = 1,2m + 3,4m + 3m = 7,6m

d) 2hm = 200m; 0,05km = 50m; 20dm = 2m

2hm + 0,05km - 20dm = 200m + 50m - 2m = 248m

e) 3,5km = 3 500m; 1dam = 10m

3,5km - 500m + 1dam = 3 500m - 500m + 10m = 3 010m

f) 200cm = 2m; 30dm = 3m

99m - 200cm - 30dm = 99m - 2m - 3m = 94m
