Сократите дробь:
а) $\frac{15a(p - q)}{20b(p - q)}$;
б) $\frac{8a^2b^3(a + b)}{20ab^2(a + b)}$;
в) $\frac{2b(m + n)}{6bc(m + n)}$;
г) $\frac{44c^3d^8(c - d)}{100c^5d^4(c - d)}$.
$\frac{15a(p - q)}{20b(p - q)} = \frac{15}{20} * a * \frac{1}{b} * \frac{p - q}{p - q} = \frac{3a}{4b}$
$\frac{8a^2b^3(a + b)}{20ab^2(a + b)} = \frac{8}{20} * \frac{a^2}{a} * \frac{b^3}{b^2} * \frac{a + b}{a + b} = \frac{2ab}{5}$
$\frac{2b(m + n)}{6bc(m + n)} = \frac{2}{6} * \frac{b}{b} * \frac{1}{c} * \frac{m + n}{m + n} = \frac{1}{3c}$
$\frac{44c^3d^8(c - d)}{100c^5d^4(c - d)} = \frac{44}{100} * \frac{c^3}{c^5} * \frac{d^8}{d^4} * \frac{c - d}{c - d} = \frac{11d^4}{25c^2}$
