☯ The denominator of a rational number is less than its numerator than 5. So, \\ \\

Let the numerator of rational number be x.

Therefore, denominator of rational number is (x - 5). \\ \\

:\implies\sf Fraction = \dfrac{x}{x - 5}\\ \\

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

\qquad\qquad\boxed{\bf{\mid{\overline{\underline{\purple{\bigstar\: According\: to \: Question :}}}}}\mid}\\ \\

☯ If 5 is added to the numerator, the new number becomes 11/6. \\ \\

:\implies\sf \dfrac{x + 5}{x - 5} = \dfrac{11}{6}\\ \\

:\implies\sf 6(x + 5) = 11(x - 5)\\ \\

:\implies\sf 6x + 30 = 11x - 55\\ \\

:\implies\sf 6x - 11x = - 55 - 30\\ \\

:\implies\sf - 5x = - 85\\ \\

:\implies\sf x = \cancel{ \dfrac{- 85}{- 5}}\\ \\

:\implies{\boxed{\frak{\pink{x = 17}}}}\;\bigstar\\ \\

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

Therefore, \\ \\

  • Numerator, x = 17

  • Denominator, (x - 5) = 17 - 5 = 12 \\ \\

\therefore Hence, The required rational number is 17/12.
