Question

The denominator of a fraction is 4 more than the numerator. If both the numerator and the denominator are increased by 1, the fraction becomes 4/5. What is the original fraction?

Answer 1

69 is not a fraction.

d = n+4
(n+1)/(d+1) = 4/5
(n+1)/(n+4+1) = 4/5
(n+1)/(n+5) = 4/5
5(n+1) = 4(n+5)
5n+5 = 4n+20
n = 15

The fraction was 15/19
