2500 cm + 0,0075 km + 0,38dam+2150mm= ........... m.
2500cm=25m

0,0075km=7,5m

0,38dam=3,8m

2150mm=2,15m

25m+7,5m+3,8m+2,15m=38,45m


4500mm2+0,000125hm2+25.000.000cm2+24m2=............. dam2

4500mm2=0,000045dam2

0,000125hm2=0,0125dam2

25000000cm2=25dam2

24m2=0,24dam2

0,000045dam2+0,0125dam2+25dam2+0,24dam2=25,252545dam2


1,25g/cm3=1,25:1000=0,00125kg/m3
