1.2 meters to millimeters
using a rule of three
1 meter =1000 millimeters, so
1.2 meters = x millimeters
[tex]\frac{1}{1000}=\frac{1.2}{x}[/tex]solve for x
[tex]\begin{gathered} \frac{1}{1000}=\frac{1.2}{x} \\ 1\cdot x=1.2\cdot1000 \\ x=1200 \end{gathered}[/tex]Therefore
1.2 meters =1200 millimeters
