Răspuns:

Explicație pas cu pas:

85 dam - 13 m =

= 8500 dm - 130 dm =

= 8370 dm

1 dam = 10 m = 100 dm

85 dam x 100 = 8500 dm

1 m = 10 dm

13 m x 10 = 130 dm

5 km - 82 m =

= 50000 dm - 820 dm =

= 49180 dm

1 km = 10 hm = 100 dam = 1000 m = 10000 dm

5 km x 10000 = 50000 dm

1 m = 10 dm

82 m x 10 = 820 dm

84 km - 15 dam =

= 84000 m - 150 m =

=  83850  m​

1 km = 10 hm = 100 dam = 1000 m

84 km x 1000 = 84000 m

1 dam = 10 m

15 dam x 10 = 150 m

Răspuns:

1. 8370 dm

2. 49180 dm

3. 838500 dm (83850 m)
