Answer:

(p/q)^-1=(4/3)^-3

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Given ;

$\frac{p}{q} = (\frac{3}{7} )^{-3} * ( \frac{21}{12} )^{-3$

⇒ $(\frac{p}{q}) ^{-1} = \frac{q}{p } =( \frac{3}{7} )^{3} * (\frac{21}{12} )^{3$

⇒ $\frac{q}{p} = \frac{27}{343} * \frac{9261}{1728} =$ $\frac{250047}{592704}$
