Vector projection ans check and derivation check

Hi all can someone please just have a look at my derivation for projection vectors and the ans to this question please. I have attached photos with my working big thanks in advance.

Find the vector which is obtained as the projection of the vector $\displaystyle A=(3,5,1)$ on the direction $\displaystyle \hat{n}=\frac{1}{\sqrt{3}}(1,1,1)$

Sorry for the side way photo they alway come out like that cannot change them
