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
