Solve the problem.A fractal is formed in the following way:Start with an equilateral triangle. Place the triangle so that one side is horizontal and so that the triangle is "pointing upward". Divide the triangle into 9 smaller equilateral triangles of equal size and remove the three triangles which are "pointing downward". Repeat this process at each stage.Find the scale factor which is equal to the ratio
