Question

4. The sum of the numerator and the denominator
of a fraction is 9. If 3 is added to each of
the numerator and the denominator, it becomes1/2
Find the fraction.​

Answer 1

Answer:

the fraction is 2/7

Step-by-step explanation:

let nr be n and dr be d

then n+d=9

and

n+3/d+3=1/2

ie. 2n+6=d+3

2n-d=-3

now we add the 2 equations we get

3n=6 so n=2

if n=2 then d=7

so the fraction is

2/7
