Question

Spune care lungime este mai mare 24 cm sau 3 dm. 35 dam sau 3 hm. 8dm sau 89 cm. 35 hm sau 4 km. 57mm sau 5 cm. 2 km sau 1800 m.

Answer 1

Răspuns:

1 dm = 10 cm

3 dm = 3 x 10 = 30 cm

24  <  30

24 cm  < 3 dm

1 hm = 10 dam

3 hm = 3 x 10 =  30 dam

35 >  30

35 dam > 3 hm

1 dm = 10 cm

8 dm = 8 x 10 = 80 cm

80 <  89

8 dm   <   89 cm

1 km = 10 hm

4 km = 4 x 10 = 40 hm

35 <  40

35 hm   <  4 km

1 cm = 10 mm

5 cm = 5 x 10 = 50 mm

57 > 50

57 mm  >  5 cm

1 km = 1000 m

2 km = 2 x 1000 = 2000 m

2000  >  1800

2 km  > 1800 m
