Question

a fraction becomes 4/5 if 1 is added to both the numerator and the denominator. if however,5 is subtracted from both numerator and denomenator, the fraction becomes 1/2.what is the fraction?

Answer 1

let fraction is x/y
1 added to both then (x+1)/(y+1)=4/5
=> 5x - 4y = -1 ------------ equation (1)
5 substracted to both then (x-5)/(y-5)= 1/2
=> 2x - y= 5 -------------- equation (2)
after solving equation 1 & 2
X = 7 and Y = 9
so fraction is 7/9
