Question

Convert the following length from $cm$ to $metres$ using decimals.

$425cm$

Answer 1

Conversion from $cm$ to $metres$:

Since, we know that

$$\begin{gathered} 1m=100cm \\ \Rightarrow 1cm=0.01m \end{gathered}$$

Thus, $$\begin{gathered} 425cm=425\times 0.01m \\ =4.25m \end{gathered}$$

Hence, $425cm=4.25m$.
