(i) \(\frac{8}{-5}\) and \(\frac{-24}{15}\)
\(\frac{8}{-5}\times\frac{-3}{-3} = \frac{-24}{15}\)
∴ The above pair of numbers represent the same rational number.
(ii) \(\frac{1}{3}\) and \(\frac{-1}{9}\)
\(\frac{1}{3}\) is a positive rational number and \(\frac{-1}{9}\) is a negative Rational Number.
Therefore this pair does not represent the same rational number.
(iii) \(\frac{-5}{-9}\) and \(\frac{5}{-9}\)
\(\frac{-5}{-9}\times\frac{-1}{-1} = \frac{5}{9}\) is a positive rational number and \(\frac{5}{-9}\) is a negative rational number.
