Answer»

GIVEN :

The numerator of a fraction is 6 less than the DENOMINATOR.

• If 3 is added to the numerator, the fraction is equal to ⅔ .

TO FIND :

ORIGINAL fraction = ?

SOLUTION :

• Let the denominator 'x' .

• So , Numerator = x - 6

▪︎ ACCORDING to the QUESTION

\\ \implies\sf \dfrac{(x - 6) + 3}{x + 3}  =  \dfrac{2}{3}  \\

\\ \implies\sf \dfrac{x - 3}{x + 3}  =  \dfrac{2}{3}  \\

\\ \implies\sf 3(x - 3)= 2(x + 3) \\

\\ \implies\sf 3x - 9= 2x + 6 \\

\\ \implies\sf 3x - 2x= 9+ 6 \\

\\ \implies\sf x= 9+ 6 \\

\\ \implies \large{ \boxed{\sf x=15 }}\\

HENCE

\\ \implies \sf \: original \:  \: fraction =  \dfrac{15 - 6}{15} \\

\\ \implies \large{ \boxed{ \sf \: original \:  \: fraction =  \dfrac{9}{15}}} \\
