Given:-

  • The numerator of a fraction is 8 less than its denominator.
  • If 2 is added to both numerator as well as denominator the fraction becomes 11 upon 19.

To Find:-

  • What's the Fraction?

Solution :-

\sf \underline {Let}

  • The denominator of the fraction be x.It’s given that the numerator of a fraction is 8 less than its denominator. So, its numerator will be (x - 8) and the fraction will be (x-8)/x.

\sf  \:  \:  \:  \:   \:  \:  \:  \:  \: \:\::\implies \dfrac{(x - 8) + 2}{x + 2}  =  \dfrac{11}{19}\\

\sf  \:  \:  \:  \:   \:  \:  \:  \:  \: \:\::\implies 19(x - 6) = 11(x + 2)\\

Solution :-

\sf \underline {Let}Let

The denominator of the fraction be x.It’s given that the numerator of a fraction is 8 less than its denominator. So, its numerator will be (x - 8) and the fraction will be (x-8)/x.

\begin{gathered}\sf \: \: \: \: \: \: \: \: \: \:\::\implies \dfrac{(x - 8) + 2}{x + 2} = \dfrac{11}{19}\\\end{gathered}:⟹x+2(x−8)+2=1911

\begin{gathered} \sf \: \: \: \: \: \: \: \: \: \:\::\implies\dfrac{x - 8 + 2}{x + 2} = \dfrac{11}{19}\\\end{gathered}:⟹x+2x−8+2=1911

\begin{gathered} \sf \: \: \: \: \: \: \: \: \: \:\::\implies\dfrac{x - 6}{x + 2} = \dfrac{11}{19}\\ \end{gathered}:⟹x+2x−6=1911

\begin{gathered}\sf \: \: \: \: \: \: \: \: \: \:\::\implies 19(x - 6) = 11(x + 2)\\\end{gathered}:⟹19(x−6)=11(x+2)

\begin{gathered}\sf \: \: \: \: \: \: \: \: \: \:\::\implies 19x - 114 = 11x + 22\\\end{gathered}:⟹19x−114=11x+22
