$\frac{b^5}{b^3}=b^2$, тогда:
$\frac{a}{b^3}=\frac{b^2\ast <!--\; \ast \; -->a}{b^2\ast <!--\; \ast \; -->b^3}=\frac{a{b}^2}{b^5}$

$\frac{27n^4}{9n}=3n^3$, тогда:
$\frac{m}{9n}=\frac{3n^3\ast <!--\; \ast \; -->m}{3n^3\ast <!--\; \ast \; -->9n}=\frac{3m{n}^3}{27n^4}$

$\frac{35x^3{y}^2}{7x^{2}y}=5xy$, тогда:
$\frac{6}{7x^{2}y}=\frac{5xy\ast <!--\; \ast \; -->6}{5xy\ast <!--\; \ast \; -->7x^{2}y}=\frac{30xy}{35x^3{y}^2}$

$\frac{24p^{9}c}{6p^5}=4p^{4}c$, тогда:
$\frac{5k}{6p^5}=\frac{4p^{4}c\ast <!--\; \ast \; -->5k}{4p^{4}c\ast <!--\; \ast \; -->6p^5}=\frac{20k{p}^{4}c}{24p^{9}c}$
