Arlene wants to create a scale drawing of the poster shown below:

a rectangle is shown. the length of the rectangle is labeled 6 inches. the width of the rectangle is labeled 9 inches.

what are the dimensions of the poster at one-third its current size?

2 in by 3 in
3 in by 3 in
18 in by 27 in
12 in by 18 in

1/3 of the dimensions means to divide the dimensions by 3. This is to figure out what 1/3 of the dimensions are.
Our length is 6, and our width is 9.
Let's divide our length first.
6/3 = 2.
Our length with 1/3 of it's original dimensions is 2.
Let's divide our width now.
9/3 = 3.
Our width with 1/3 of it's original dimensions is 3.
Our dimensions are 2 by 3.
Your answer is A.) 2 in. by 3 in.
I hope this helps!
