To find the value of \(\frac{\Sigma_{r=1}^{n} \frac{1}{r}}{\Sigma_{r=1}^{n} \frac{k}{(2n-2k+1)(2n-k+1)}}\), we will break down the problem step by step. ### Step 1: Understand the Summations We have two summations to evaluate: 1. The numerator: \(\Sigma_{r=1}^{n} \frac{1}{r}\) 2. The denominator: \(\Sigma_{r=1}^{n} \frac{k}{(2n-2k+1)(2n-k+1)}\) ### Step 2: Evaluate the Numerator ...
