Answer 2

a) 2 h 6 min = ..... min
2 h = 60 Min × 2
2 h = 120 Min
120 min + 6 min = 126 min

b) 12 hg + 5 kg = ...... dag
12 hg = 120 dag
5 kg = 500 dag
120 dag + 500 dag = 620 dag

c) 400 cl + 20 dl = ..... l
400 cl = 4 l
20 dl = 2 l
4 l + 2 l = 6 l

d) 6 cm³ + 0,004 dm³ = ..... mm³
6 cm³ = 6000 mm³
0,004 dm³ = 4000 mm³
6000 mm³ + 4000 mm³ = 10000 mm³

e) 9 hm² + 200 m² = ...... dam²
9 hm² = 900 dam²
200 m² = 2 dam²
900 dam² + 2 dam² = 902 dam²

f) 5 hm + 6 dam + 80 dm = ..... m
5 hm = 500 m
6 dam = 60 m
80 dm = 8 m
500 m + 60 m + 8 m = 568 m
