一张边长 英寸的正方形纸沿竖直方向对折。然后将两层纸沿平行于折痕的方向切成两半。形成三个新的长方形：一个大的和两个小的。一个小长方形的周长与大长方形周长之比是多少？
A square piece of paper, inches on a side, is folded in half vertically. Both layers are then cut in half parallel to the fold. Three new rectangles are formed, a large one and two small ones. What is the ratio of the perimeter of one of the small rectangles to the perimeter of the large rectangle?
小提示：
对折后，纸变成一个 的长方形
After folding, the paper is a rectangle
大提示：
小长方形是
The small rectangles are
解答：
正方形对折后形成一个 的长方形。
将折叠后的纸沿平行于折痕的方向切成两半，得到两个 的小长方形和一个 的大长方形。
一个小长方形周长与大长方形周长之比为
所以正确答案是 E。
The square is folded in half to create a rectangle.
Cutting the folded paper in half parallel to the fold gives two small rectangles and one large rectangle.
The ratio of the perimeter of a small rectangle to the perimeter of the large rectangle is
Thus, E is the correct answer.
