# If 3 centimeters is equal to 30 millimeters, how many centimeters are in 140 millimeters?

$14 \text{ cm}$

#### Explanation:

The following $\textcolor{b l u e}{\text{conversion}}$ is used to convert mm (millimetres) to cm (centimetres) or vice-versa.

$\textcolor{red}{\overline{\underline{| \textcolor{w h i t e}{\frac{2}{2}} \textcolor{b l a c k}{1 \text{ cm" = 10" mm}} \textcolor{w h i t e}{\frac{2}{2}} |}}}$

That is to calculate the number of cm for a given number of mm, $\textcolor{b l u e}{\text{divide by 10}}$

rArr(140"mm")/10=14"cm"
