Answer:

numerator = 2 and denominator is 4

Step-by-step explanation:

let the denominator be x

numerator = x-2

according to the question

[tex]\frac{x-2}{x} = \frac{1}{2}[/tex]

do cross multiplication

x*1 = 2(x-2)

x = 2x -4

4 = 2x - x

4 = x

therefore denominator is 4

numerator = x-2

=4-2

=2
