the numerator of a fraction is 5 less than the denominator.if 1 is added to both the numerator and the denominator the fraction becomes 2/3. find the fraction

  • algebra -

    We can choose to write the fraction as
    x/(x+5). That will satisfy the first requirement about the numerator being 5 less than the denominator.

    We are also told that
    (x+1)/(x+6) = 2/3
    Now solve for x.
    x + 1 = (2/3)x + 4
    x/3 = 3
    x = 9
    So the fraction is 9/14.
