Answer:

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 ?

\large \dag† Answer :-

\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}

x

x+14

=

4

11

\maltese \:✠ On Cross Multiplying ;

\begin{gathered}:\longmapsto \rm11x = 4(x + 14) \\ \end{gathered}

:⟼11x=4(x+14)

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

:⟼11x=4x+56

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

:⟼11x−4x=56

\begin{gathered}:\longmapsto \rm 7x = 56 \\ \end{gathered}

:⟼7x=56

\begin{gathered}:\longmapsto \rm x = \cancel \frac{56}{7} \\ \end{gathered}

:⟼x=

7

56

\begin{gathered}\purple{ \large :\longmapsto \underline {\boxed{{\bf x = 8} }}} \\ \end{gathered}

:⟼

x=8

\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,

\large\underline{\pink{\underline{\frak{\pmb{ Original \: Fraction = \dfrac{8}{11} }}}}}

Original Fraction =

11

8

Original Fraction =

11

8
