Question

The length of a rectangular room is$12\mathrm{m}$ and its width is $6.8\mathrm{m}$. Find the ratio of its length to its width.

Answer 1

Given:

Length of a room $=12\mathrm{m}$

Width of a room :$=6.8\mathrm{m}$

The ratio of its length to its width$=\frac{\mathrm{Length}}{\mathrm{Width}}$

$$\begin{gathered} =\frac{12\mathrm{m}}{6.8\mathrm{m}} \\ =\frac{120}{68}\left[\mathrm{Note}:\mathrm{HCF}\left(120,68\right)=4\right] \\ =\frac{30}{17} \\ =30˸17 \end{gathered}$$

Hence, the ratio of its length to its width is $30˸17$
