Answer:

The fraction is  [tex]\frac{6}{13} .[/tex]

Step-by-step explanation:

There is a data missing in the question so the complete question is below:

If 1 is added to both numerator and denominator of a fraction,the fraction become 1/2 if 8 is added to both, the fraction become 2/3 what is the fraction?

Now, to find the fraction.

Let the fraction be [tex]\frac{x}{y} .[/tex]

If 1 is added to both numerator and denominator of a fraction,the fraction become 1/2.

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

By cross multiplying we get:

[tex]2x+2=y+1[/tex]

Subtracting both sides by [tex]1[/tex] we get:

[tex]2x+1=y[/tex]

[tex]y=2x+1[/tex]    ......(1)

Now, if 8 is added to both, the fraction become 2/3:

[tex]\frac{x+8}{y+8} =\frac{2}{3}[/tex]

By cross multiplying we get:

[tex]3x+24=2y+16[/tex]

Subtracting both sides by 16 we get:

[tex]3x+8=2y[/tex]

Substituting the value of [tex]y[/tex] from equation (1) we get:

[tex]3x+8=2(2x+1)[/tex]

[tex]3x+8=4x+2[/tex]

Adding both sides by 2 we get:

[tex]3x+6=4x[/tex]

Subtracting both sides by 3[tex]x[/tex] we get:

[tex]6=x[/tex]

[tex]x=6.[/tex]

Now, substituting the value of [tex]x[/tex] in equation (1):

[tex]y=2x+1\\y=2\times 6+1\\y=12+1\\y=13.[/tex]

Therefore, the fraction is  [tex]\frac{6}{13} .[/tex]
