Since we have given that
Length of yard of string to hang 3 banners is given by
![(11)/(12)](https://img.qammunity.org/2019/formulas/mathematics/college/f34b982z8x4l4gq2phwvamci1vexeihsru.png)
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
![(3)/((11)/(12))\\\\=3.27\text{ yard of string }](https://img.qammunity.org/2019/formulas/mathematics/college/4x7fe8w9ulhzpzknopnh3sj1wl90o82ep6.png)
Hence, 3.27 yard of string to hang each banner.
