Question

transformati in m:
3800 mm
2150 mm
420 dam
480 mm
1800 dm
20 cm
0,05 hm
0,005 mm
100 hm

Answer 1

3800 mm=3,8 m
2150 mm=2,15 m
420 dam=4200 m
480 mm=0,48 m
1800 dm= 180 m
20 cm= 0,2 m
0,05 hm=5 m
0,005 mm= 0,000005 m
100 hm= 10000 m

Answer 2

3800mm =3800:10^3 =3800:1000 =3.8 m
2150mm =2150:10^3 =2150:1000 =2.15 m
420dam =420*10 =4200m
480mm=480:10^3 =480 :1000=0.48 m
1800dm =1800:10 =180 m
20cm =20 :10^2 =20:100 =0.20 m
0.05hm =0.05 *10^2 =0.05*100 =5 m
0.005mm =0.005 :10^3 =0.005:1000 =0.000005 m
100hm =100*10^2 =100*100 =10000 m
