Answer 2

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 $\sf\dfrac{x-8}{x}$.

⠀⠀⠀⠀⠀$\small\underline{\pmb{\sf According \: to \: the \: question :-}}$

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

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

$\sf \: \: \: \: \: \: \: \: \: \:\::\implies\dfrac{x - 6}{x + 2} = \dfrac{11}{19}$

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

$\sf \: \: \: \: \: \: \: \: \: \:\::\implies 19x - 114 = 11x + 22$

$\sf \: \: \: \: \: \: \: \: \: \:\::\implies 19x - 11x = 22 + 114$

$\sf \: \: \: \: \: \: \: \: \: \:\::\implies 8x = 136$

$\sf \: \: \: \: \: \: \: \: \: \:\::\implies x = \cancel\dfrac{136}{8}$

$\sf \: \: \: \: \: \: \: \: \: \:\::\implies{\underline{\boxed{\frak{\pink{x =17}}}}}\:\bigstar$

Hence:-

$\dag\underline{\sf\green{{\sf The\: Denominator\: of \: the\: fraction:- }}}$

$\sf:\implies \boxed{ \sf x = 17.}$

$\dag\underline{\sf\green{{\sf The\: \: of \:Numerator the\: fraction:- }}}$

$\sf:\implies x - 8 = 17 - 8.$

$\sf:\implies \boxed{ \sf Numerator = 9.}$

$\therefore\:\underline{\textsf{The fraction will be \textbf{9/17}}}.$
