Answer 1

$(\frac{q}{4v} - \frac{v}{q})\cdot (\frac{2}{q-2v}) = (\frac{q\cdot q- v \cdot4v}{4v\cdot q}) \cdot (\frac{2}{q-2v}) = (\frac{q^2-4v^2}{4v\cdot q})\cdot (\frac{2}{q-2v}) =\newline \frac{(q-2v)(q+2v)2}{4v\cdotq(q-2v)} = \frac{2(q+2v)}{4v}|_{q=1/5, v=1/6} = \frac{\frac{1}{5} + 2\cdot \frac{1}{6}}{2*\frac{1}{6}} = 1.6$
