Answer: 3.27 yard of string to hang each banner.
Step-by-step explanation:
Since we have given that
Length of yard of string to hang 3 banners is given by
[tex]\frac{11}{12}[/tex]
Now, we'll use the unitary method to find the length of yard of string is used for banner,
So,
Length of yard of string to hang 1 banner is given by
[tex]\frac{3}{\frac{11}{12}}\\\\=3.27\text{ yard of string }[/tex]
Hence, 3.27 yard of string to hang each banner.
