(i) x/1 = (x + 1)/x implies x²  x  1 = 0, whose positive root is the golden ratio. (ii) y/x = (x + y)/y implies y/x = (1 + y/x)/(y/x), so the answer is "yes". (iii) Have a go at this. At least one method is very easy. (iv) The biggest rectangle is a square. Please post your attempt for this question.
