Nice way to show the reason for the standard algorithm: we multiply numerator and multiply denominator because the bottom multiplication is how many "out of squares" we make (20 : the big square must be 4 X 5!) and the numerator product is the "how many squares" we have! Love it! (And I confess makes me want to teach the standard algorithm more - supported now by a great visual 😜)
