A voyage of discovery through a sequence of challenges exploring properties of the Golden Ratio and Fibonacci numbers.

Find the link between a sequence of continued fractions and the ratio of succesive Fibonacci numbers.

Solve quadratic equations and use continued fractions to find rational approximations to irrational numbers.

An article introducing continued fractions with some simple puzzles for the reader.

An iterative method for finding the value of the Golden Ratio with explanations of how this involves the ratios of Fibonacci numbers and continued fractions.

In this article we are going to look at infinite continued fractions - continued fractions that do not terminate.

The tangles created by the twists and turns of the Conway rope trick are surprisingly symmetrical. Here's why!

Which of these continued fractions is bigger and why?

This article sets some puzzles and describes how Euclid's algorithm and continued fractions are related.

A personal investigation of Conway's Rational Tangles. What were the interesting questions that needed to be asked, and where did they lead?

Which rational numbers cannot be written in the form x + 1/(y + 1/z) where x, y and z are integers?

Use Euclid's algorithm to get a rational approximation to the number of major thirds in an octave.

In this article we show that every whole number can be written as a continued fraction of the form k/(1+k/(1+k/...)).

Explore the continued fraction: 2+3/(2+3/(2+3/2+...)) What do you notice when successive terms are taken? What happens to the terms if the fraction goes on indefinitely?
