Question

the denominator of a fraction is 2 more than its numerator. 7 is added to numerator and 2 is substracted from denominator,the fraction becomes 2.Find the fraction​

Answer 1

Answer:

$let \:the \: numerator \: be \: x.$

$the n\: denominator =( x + 2)$

$Atq,$

$\: \: \: \: \: \: \frac{x + 7}{(x + 2) - 2} = 2 \\ = > \frac{x + 7}{x} = 2 \\ = > x + 7 = 2x$

$= > x - 2x = - 7$

$= > - x = - 7$

$= > x = 7$

$Hence, required fraction = \frac{7}{9}$
