This is a short, animated visual proof demonstrating what one might called the mediant inequality.

If you like this video, consider subscribing to the channel or consider buying me a coffee: www.buymeacoffee.com/VisualProofs. Thanks!

This animation is based on a visual proof by Richard A. Gibbs from the June 1990 issue of Mathematics Magazine (doi.org/10.2307/2691137 - page 172).

Unbelievable.....power of computer animation...I never understood maths since 1986 math classes but now I see how simple was.. thanks for your content.

A very nice visualization of the idea

From the triangle shown, (a+c)/(b+d) >= c/d. Maybe the triangle is not drawn correctly. However, the issue with this visualization is, how did we assume that the slope a/b <= (a+c)/(b+d) ?

Also known as naive fraction addition (since is the “wrong” way to add fractions when you first learn it 😂)

That aside, the mediant operation and the inequality are useful for finding rational approximations of irrational numbers using a method known as the Farey algorithm.

One small caveat is that you can only use the operation when the two fractions are in their simplest form i.e. irreducible in order to obtain a unique output from the operatio

Or, define a Mediant function M(a, b, c, d)

I think it works only if all the numbers are positive. (Of course a and c may be zero)

What is that symbol at the end that has a plus + sign in a circle ⭕ ?

I don't think this operation is well-defined. 3/6=1/2 but 3/6+1/5 isn't equal to 1/2+1/5.

but it doesn't make sense still... because 1/2 ++ 2/2 is 3/4 but it's also equal to 2/4 ++ 1/1 which is 3/5 so... basically the result is anything inbetween the two parameters.

the mediant is not well defined with respect to the representation chosen
