{ ∫ from 0 to L of x(M/L) dx}/{ ∫ from 0 to M of dm} = ?
I think the answer is L/2. Am I right?
Edit:
My bad. I entered wrong data in the numerator.I have corrected it now.

$\displaystyle \frac{\int_0^L \frac{M}{L}x \ \mathrm{d}x}{\int_0^M \mathrm{d}m}$$\displaystyle =\frac{\left[ \frac{Mx^2}{2L}\right]_{x=0}^L}{\left[m\right]_{m=0}^M }$$\displaystyle = \frac{\frac{ML^2}{2L} - 0}{M-0} = \frac{\frac{ML}{2} - 0}{M} = \frac{ML}{2M} =\frac{L}{2}$
