The numerator of a fraction is 1 less than the denominator if 4 is added to both the numerator and denominator the fraction becomes 8/4 find the fraction

The fraction is

Let the denominator of fraction be "a"

Given that numerator of a fraction is 1 less than the denominator

numerator of a fraction = denominator - 1

So the numerator of a fraction = a - 1

Thus the required fraction is:

Also given that if 4 is added to both the numerator and denominator the fraction becomes 8/4

Thus the original fraction is:

Thus the fraction is

3/5
