Let $\mathbf{a},$ $\mathbf{b},$ and $\mathbf{c}$ be unit vectors, such that the angle between $\mathbf{a}$ and $\mathbf{b}$ is $\arccos \frac{1}{5},$ the angle between $\mathbf{a}$ and $\mathbf{c}$ is $\arccos \frac{1}{6},$ and the angle between $\mathbf{b}$ and $\mathbf{c}$ is $60^\circ.$

Let $P$ be the plane which contains the origin, $\mathbf{b},$ and $\mathbf{c}.$  Then the projection of $\mathbf{a}$ onto $P$ can be expressed in the form
\[p \mathbf{b} + q \mathbf{c}\]for some scalars $p$ and $q.$  Enter the ordered pair $(p,q).$
From the given information, $\mathbf{a} \cdot \mathbf{b} = \frac{1}{5},$ $\mathbf{a} \cdot \mathbf{c} = \frac{1}{6},$ and $\mathbf{b} \cdot \mathbf{c} = \cos 60^\circ = \frac{1}{2}.$

Let $\mathbf{p}$ be the projection of $\mathbf{a}$ onto plane $P.$  Let $\mathbf{n}$ be a unit vector that is normal to plane $P,$ on the same side of plane $P$ as vector $\mathbf{a}.$  Then
\[\mathbf{a} = p \mathbf{b} + q \mathbf{c} + r \mathbf{n}\]for some scalar $r.$

Taking the dot product with $\mathbf{b},$ we get
\[\mathbf{a} \cdot \mathbf{b} = p \mathbf{b} \cdot \mathbf{b} + q \mathbf{b} \cdot \mathbf{c} + r \mathbf{b} \cdot \mathbf{n}.\]This reduces to $\frac{1}{5} = p + \frac{q}{2}.$

Taking the dot product with $\mathbf{c},$ we get
\[\mathbf{a} \cdot \mathbf{c} = p \mathbf{b} \cdot \mathbf{c} + q \mathbf{c} \cdot \mathbf{c} + r \mathbf{c} \cdot \mathbf{n}.\]This reduces to $\frac{1}{6} = \frac{p}{2} + q.$

Solving the system in $p$ and $q,$ we find $(p,q) = \boxed{\left( \frac{7}{45}, \frac{4}{45} \right)}.$
