THE QUESTION

The numerator of a fraction is 4 less than the denominator. If 1 is added to both its numerator and denominator, it becomes 1/2

Find the fraction.

The Answer

Let the fraction be

Let the fraction be b

Let the fraction be ba

Let the fraction be ba

Let the fraction be ba

Let the fraction be ba Numerator= denominator-4

Let the fraction be ba Numerator= denominator-4a=b−4⇒b−a=4

Let the fraction be ba Numerator= denominator-4a=b−4⇒b−a=4If 1 added to both numerator and denomator then fraction = 1/2

b+1

b+1a+1

=1/2

2a+2=b+1

2a+2=b+12a−b=−1

2a+2=b+12a−b=−1(2a−b)+(b−a)=4−1

2a+2=b+12a−b=−1(2a−b)+(b−a)=4−1a=3,b=7

2a+2=b+12a−b=−1(2a−b)+(b−a)=4−1a=3,b=7 Fraction= 3/7 (Ans:-)
