Divide 1 and 1/3 by 12. To get the answer

Answer 2

Answer: There are 9 banners that can be made from 12 sections of plastic.

Step-by-step explanation:

Since we have given that

Number of banners which require $1\frac{1}{3}=\frac{4}{3}$ sections of the plastic = 1

We will use the " Unitary method", we get

Number of banners which require 1 section of the plastic is given by

$\frac{3}{4}$

Number of banners which requires 12 sections  of the plastic is given by

$\frac{3}{4}\times 12\\\=3\times 3\\\\=9$

Hence, there are 9 banners that can be made from 12 sections of plastic.
