Heya !!!
Let the denominator of the fraction be X.
Numerator or the fraction = (X-3)
Fraction = Numerator/Denominator = (X-3)/X
Numerator is increased by 1 = (X-3+1) = (X-2)
And,
Denominator is increased by 3 = (X+3)
Fraction = Numerator/Denominator = (X-2)/(X+3)
According to question,
(X-2)/(X+3) = 1/2 × (X-3)/ X
X-2 / X +3 = X-3 / 2X
2X(X-3) = (X+3) (X-3)
2X² - 6X = (X)² - (3)²
2X² - X² -6X + 9 = 0
X² - 6X + 9 = 0
X² -3X - 3X + 9 = 0
X(X-3) -3 ( X -3) = 0
(X-3) ( X -3) = 0
(X-3) = 0
X = 3
Denominator of Fraction = X = 3
and,
Numerator of fraction = X -3 = 3 -3 = 0
Fraction = Numerator/Denominator = 0/3
