Question

the numerator of a fraction is 4 less the denominator. if 1 is added to both its ne.erator and denominator,it becomes 1/2. find the fraction ​

Answer 1

Answer:

let numerator be n and denominator be d

n = d-4

n+1/d+1 =1/2

2(n+1) = d+1

2n+2 =d+1

2(d-4)+2 = d+1

2d-8+2 = d+1

d = 7

n = d-4 = 3

fraction is 3/7
