### Instruction: An equilateral triangle and a square have the same perimeter of 12 inches. What is the ratio of the side length of the triangle to the side length of the square? Express your answer as a common fraction.### Response: I know that an equilateral triangle has three congruent sides, and a square has four congruent sides.
So, if the perimeter of both figures is 12 inches, I can divide 12 by the number of sides to get the side length of each figure.
For the triangle, I divide 12 by 3 and get 4 inches for each side.
For the square, I divide 12 by 4 and get 3 inches for each side.
To find the ratio of the side length of the triangle to the side length of the square, I divide 4 by 3 and get 4/3.
