Đáp án: 

\(\begin{align}
  & a)\text{ }50\text{ }cm\text{ }=0,5\text{ }m\text{ }=0,0005\text{ }km \\ 
 & \text{ }b)\text{ }0,04\text{ }km\text{ =40 }m\text{ }=40000mm \\ 
 & \text{ }c)\text{ }3,5\text{ }kg\text{ }=\text{ 3500 }g \\ 
 & \text{ }d)\text{ }1600\text{ }g\text{ }=1,6\text{ }kg\text{ } \\ 
 & e)\text{ }7\text{ }lang\text{ }=0,7kg\text{ }=700g \\ 
 & \text{ }f)\text{ }0,1\text{ }{{m}^{3}}\text{ }=\text{ }100\text{ }d{{m}^{3}}\text{ }=100\text{ }l\text{ } \\
