The reciprocal of a fraction is its "inverse" . When the reciprocal is multiplied by the original number, the product will always be one. Therefore the reciprocal of $\frac{ 7 }{ 2a} = \frac{ 2a }{7}$

apply this rule to your fraction: $$\dfrac{1}{\dfrac{a}{b}} = \dfrac{b}{a}$$ where $$\dfrac{a}{b}$$ is your fraction.
