Question

Consider the statement: Ratio of breadth and length of a hall is 2 : 5. Complete the following table that shows some possible breadths and lengths of the hall.

Breadth of the hall (in meters)	10	$\square$	40
Length of the hall (in meters)	25	50	$\square$

Answer 1

Ratio of breadth to length $= 2 : 5 = \frac{2}{5}$
∴ Other equivalent ratios are $=\frac{ 2}{5} ×\frac{ 10}{10} =\frac{ 20}{50}, \frac{2}{5} × \frac{20}{20}$
$= \frac{40}{100}$
Thus,

Breadth of the hall (in meters)	10	20	40
Length of the hall (in meters)	25	50	100
