Question

Convert $65cm$ into $mm,m$ and $km$.

Answer 1

As we know,

$$\begin{gathered} 1cm=10mm \\ 1cm=\frac{1}{100}m \\ 1cm=\frac{1}{100000}km \end{gathered}$$

$65cm=65\times 10mm=650mm.$

$65cm=65\times \frac{1}{100}m=\frac{65}{100}m=0.65m$.

$65cm=65\times \frac{1}{100000}km=\frac{65}{100000}km=0.00065km$

Hence, above are the required result.
