Question :-
The denominator of a rational number is greater than its numerator by 3, if numerator is increased by 14 and denominator is decreased by 3 the new number becomes 11 by 4 what is the rational number ?

\begin{gathered}\red\dashrightarrow\underline{\underline{\sf \green{The \: Original \: Number \: is \: \frac{8}{11} }} }\\\end{gathered}

The Original Number is
11
8
\large \dag† Step by step Explanation :-
Let Numerator and Denominator of Original Rational Number be :
Numerator = x
As Per the question denominator of the rational number is greater than its numerator by 3 so,
Denominator should be = x + 3
Hence,
\begin{gathered}\text{Original Number = } \frac{\text x}{\text x + 3} \\ \end{gathered}
Original Number =
x+3
x
❒ When numerator is increased by 14 and denominator is decreased by 3 :
\begin{gathered} \rm \text{Number Becomes } : \frac{x + 14}{x} \\ \end{gathered}
Number Becomes :
x
x+14
⏩ According To Question :
\begin{gathered} \large \blue \bigstar \: \: \red{ \bf \frac{ x + 14 }{x} = \frac{11}{4} } \\ \end{gathered}
★

\begin{gathered}:\longmapsto \rm 11x - 4x = 56 \\ \end{gathered}

\begin{gathered}\blue\dashrightarrow\underline{\underline{\sf \orange{Numerator \: of \: Original \: Number = 8 }} }\\ \end{gathered}
⇢
Numerator of Original Number=8
☆ As The denominator of the rational number is greater than its numerator by 3
\begin{gathered}\rm\therefore \: Denominator = 8 + 3\\ \end{gathered}
∴ Denominator =8 +3
\begin{gathered}\blue\dashrightarrow\underline{\underline{\sf \orange{Denominator \: of \: Original \: Fraction = 11 }} }\\ \end{gathered}
⇢
Denominator of Original Fraction=11
Therefore,

Original Fraction =
11
8
Original Fraction =
