Answer 2

Answer:

$\huge\blue\boxed{answer}$

Let's assume that

denominator = y, numerator = X

So their sum

x+y = 9

y = 9-x

and if 3 is added to both their fraction become

$\frac{x + 3}{y + 3} = \frac{1}{2}$

Cross multiple

2x +6 = y +3

putting value of y

2x +6 = (9-x) +3

2x +6 = 9 - X +3

2x +X = 12 +6

3x = 18

x = 18/3

x = 6

y = 9-x

so, y = 9-6

y = 3
