numerator and denominator , it becomes
1 2
Find the fraction.​

Answer 1

Answer:

3/7

Step-by-step explanation:

Let numerator be x then denominator is x+4

hence the fraction is x/(x+4)

Next, numerator becomes x+1

and denominator becomes x+5

thus, (x+1)/(x+5) = 1/2 {Given}

=> 2× (x+1) = (x+5)

=> 2x + 2 = x + 5

=> x = 3

hence the given fraction is 3/7
