Question

every positive rational number can be written as a finite sum of distinct numbers of the form 1/n where n is natural

I don't quite understand this question. Actually, what does distinct numbers of the form $1/n$ mean? Does it mean $m(1/n)$ or $(1/n)^m$? Can anyone express $17/15$ as an example?

Answer 1

No, "distinct numbers of the form $\frac{1}{n}$" refers to numbers like $\frac{1}{2}$, $\frac{1}{3}$, $\frac{1}{4}$, etc. There is no "m" as numerator or exponent. The "distinct" means that all the denominators are different.
