Frankie folded a piece of paper 12 inches by 9 inches into sections as shown below. What fraction of the total area is in each section

Option B.  

Step-by-step explanation:

The picture of the question and the options in the attached figure

we know that

The dimensions of the piece of paper is 12 inches by 9 inches

The total area is (12)(9)=108 square inches

Frankie folded a piece of paper into three sections

The dimensions of each piece of paper is

4 inches by 9 inches

The area of each piece of paper is

(4)(9)=36 square inches

therefore

To find out what fraction of the total area is each section , divided the area of one section by the total area

so
