1 feet = 12 inches
9 feet = 12 x 9 inches = 108 inches
[tex]\frac{12}{108} = \frac{12\times 1}{12\times 9} = \frac{1}{9}[/tex]
Your answer is:
[tex]\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\frac{1}{9}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}[/tex]
