Answer 1

Answer:

Let, the numerator of rational number be x then

" denominator of rational number be X+4

And both the denominator and numerator increased by one

So We make this equation

X+1/X+4+1 = 1/2

X+1/X+5 = 1/2

Step-by-step explanation:

2(X+1) = 1( X+5)

2X+2 = x+5

2X-x = 5-2

X= 3

So the number is 3Ans
