Answer:
c. [tex]\frac{1}{12n} = {[12n]}^{-1}[/tex]
Step-by-step explanation:
[tex][\frac{1}{4}][\frac{2}{5}][\frac{1}{2}][\frac{4}{7}][\frac{5}{8}][\frac{2}{3}][\frac{7}{n}] = \frac{560}{6720n} = [12n]^{-1} = \frac{1}{12n}[/tex]
[tex]\frac{2}{3} = \frac{6}{9}\\ \\ \frac{1}{2} = \frac{3}{6}[/tex]
* To make this simpler, reduce these two fractions in lowest terms.
