From the pair of linear equations in the foIlowing problems find their solution by substitution method: A fraction becomes `9/11`. If 2 is added to both the numerator and the denominator. If , 3 is added to both the numerator and the denominator it becomes `5/6` Find the fraction.

Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method :-A fraction becomes 3/4 if 1 is subtracted from denominator. If 3 is added to both the numerator and denominator, it becomes 5/6 . Find the fraction.

Form the pair of linear equations in the following problems and find their solution by substitution method : A fraction reduces to 1/4 when 2 is subtracted from the numerator and 3 is added to the denominator. But it reduces 2/3 if 6 is added to the numerator and denominator is multiplied by 3. Find the fraction.
