Inequality help

Can someone help me prove the inequality, $$\frac{\sum\limits_{k=1}^n \Lambda(k) \frac{k}{n}\lceil\frac{n}{k}\rceil\{ \frac{n}{k} \}}{\sum\limits_{k=1}^n \Lambda(k)}<\ \frac{\sum\limits_{k=1}^n 1* \frac{k}{n}\lceil\frac{n}{k}\rceil\{ \frac{n}{k} \}}{\sum\limits_{k=1}^n 1}$$

and integrate the following function from x=0 to x=1 $$x\lceil\frac{1}{x}\rceil\{ \frac{1}{x} \}$$

Where { n/k } is the fractional part of n/k , $\lceil{n}/{k}\rceil{}$ is the ceiling function applied to n/k, and where $\Lambda(k)$ is the Von-Mangoldt function.
