Problema Solution
In a certain fraction, the denominator is 2 less than the numerator. If 1 is added to both the numerator and the denominator, the resulting fraction is equal to 4/3. Find the original fraction.
Answer provided by our tutors
let 'x' represent the numerator of the original fraction, then 'x-2' represents the denominator
if 1 is added to both the numerator and the denominator, the resulting fraction is equal to 4/3:
(x+1)/(x-2+1) = 4/3
solving for 'x' we have x=7
7-2 = 5
the original fraction, then, was 7/5
