It is possible to write any number as a sum of unit fractions (fractions with 1 on top) with different denominators. For example, 3/5 = 1/2 + 1/10. Starting from the expression 1 = 1/6 + 1/6 + 1/6 + 1 ...

We show that the height density of a finite sum of fractions is zero. In fact, we give quantitative estimates in terms of the height function. Then, we focus on the unit fraction solutions in the ring ...
