1 740 dm + 27 dam + 15 hm + 5 600 cm + 2 000 m = km
280 hg + 1 200 dag = kg
1 500 g + 150 dag = g = kg
150 000 cg + 12 500 dg = g
1 500 ml + 50 cl + 10dl = cl = l

Answer 1

● 1 740 dm + 27 dam + 15 hm + 5 600 cm + 2 000 m = km

1 740 dm = 0,1740 km
27 dam=0,27 km
15 hm = 1,5 km
5 600 cm = 0,05600 km
2 000 m = 2 km

0,1740 km + 0,27 km + 1,5 km + 0,05600 km + 2 km = 4 km


● 280 hg + 1 200 dag = kg

280 hg = 28 kg
1 200 dag=12 kg

28 kg + 12 kg = 40 kg


● 1 500 g + 150 dag = g = kg

150 dag = 15 g

1 500 g + 15 g = 1 515 g = 1,515 kg


● 150 000 cg + 12 500 dg = g

150 000 cg = 1 500 g
12 500 dg = 1 250 g

1 500 g + 1 250 g = 2 750 g


● 1 500 ml + 50 cl + 10dl = cl = l

1 500 ml = 150 cl
10 dl = 100 cl

150 cl + 50 cl + 100 cl = 300 cl = 3 litri
