e) 82,5 hm + 6 hm

Answer 1

a) 4050 m
b) 676,6 m
c) 202,146 m
d) 10725 m
e) 8850 m

Answer 2

A) 3,6km ⠂1000 = 3.600m

3.600m + 450m = 4050m

B) 6,8hm ⠂100 = 680m

0.34dam ⠂10 = 3.4m

680m - 3,4 = 676.6m

C)16dm : 10 = 1.6m

54.6cm ⠂1 = 0.546m

200mm : 1000 = 0.2m

1.6m + 0.546m + 0.2m = 2,346 m

D) 2.4km ⠂1000 = 2400m

82hm ⠂100 = 8200m

12.5dam ⠂ 10 = 125m

2400m + 8200m + 125m = 10.725 m

E) 82,5 hm + 6 hm = 88.5hm

88.5hm ⠂100 = 8850m
