First you had to cancel by the fraction.
[tex]\frac{6}{9}= \frac{2}{3}[/tex]
[tex]\frac{2}{3}- \frac{1}{8}[/tex]
[tex]\frac{16}{24}- \frac{3}{24}[/tex]
Since the denominators are equal, then you had to combine by the fraction.
[tex]\frac{16-3}{24}[/tex]
Finally, you had to subtract by the numbers.
[tex]16-3=13[/tex]
[tex]10+3=13[/tex]
[tex]\frac{13}{24}[/tex]
Final answer: [tex]\boxed{=13/24}[/tex]
Hope this helps!
