Question

The length of a young gram plant is $65\mathrm{mm}$. Express its length in $\mathrm{cm}$.

Answer 1

Solution.

Given that the length of a young gram plant is $65\mathrm{mm}$

We have to convert it into $\mathrm{cm}$.

$$\begin{gathered} \therefore 65\mathrm{mm}=(65\times 0.1)\mathrm{cm}\left[\because 1\mathrm{mm}=0.1\mathrm{cm}\right] \\ \Rightarrow =6.5\mathrm{cm} \end{gathered}$$

Hence, the length of a young gram plant is $6.5\mathrm{cm}$.
