Question

T the numerator of a fraction is 4 less than the denominator if 1 is added to both its numerator and denominator it became ½ to find a fraction

Answer 1

Let the denominator be x.

So, numerator will be x-4.

According to Question , if 1 is added to both numerator and denominator , the new fraction is 1/2 →

(x-4+1)/(x+1) = 1/2

or, 2(x-3) = x+1

or, 2x-6 = x+1

or, 2x-x = 1+6

or, x = 7

Therefore , denominator is 7

Numerator = x-4 = 7-4 = 3

Fraction = 3/7

Answer → The fraction is 3/7.
