Answer 1

Răspuns:

Explicație pas cu pas:

a) 570 hm : 3 = 190 hm = 19 km  

64 000 m : 4 = 16 000 m = 160 hm  

16 km x 3 = 48 km = 4800 dam  

7 cm x 21 = 147 cm = 1470 mm

b) 16 x 15 dam = 240 dam = 2400 m  

70 dm : 2 = 35 dm = 3500 mm  

165 000 cm :3 = 55 000 cm = 55 dam  

20 000 m : 5 = 20 km : 5 = 4 km​

Answer 2

a)570hm : 3=190hm =19 km

64000m :4 =16000m=160 hm

16 km x 3 = 48 km = 4800 dam

7 cm x 21 = 147= 1470 mm

b) 16 x 15 dam=240 dam =2400 m

70 dm : 2 = 35 dm = 3500 mm

165000 cm : 3 = 55000 cm = 55 dam

20000 m : 5 = 4000 m = 4 km
