Question

Express as centimetres using decimals: $60mm$

Answer 1

Express the given unit in centimetres

As we know that, $1cm=10mm$

So, we can convert millimetres into centimetres by dividing it with $10$.

Given, $60mm$

Using unitary method, we get,

$$\begin{gathered} \Rightarrow 10mm=1cm \\ \Rightarrow 1mm=\frac{1}{10}cm \\ \Rightarrow 60mm=\frac{60}{10}cm \\ \Rightarrow 60mm=6cm \end{gathered}$$

Therefore, $60mm$ can be written as $6cm$.
