Huh — the left-hand portion of the expression is the same as the formula for the error ε of approximating r using a rational fraction a / b. In other words, the inequality seems to be saying that, as a consequence of the pigeonhole principle, we can pick any r and any K 0, and there’s always some integer a / b that approximates r with an error of less than 1 / (K · b).
