Explicación paso a paso:

de ⇒ multiplicación

$\frac{4}{6}\cdot \:6\\\\\mathrm{Convertir\:a\:fraccion}:\quad \:6=\frac{6}{1}\\\\=\frac{4}{6}\cdot \frac{6}{1}\\\\Cancelar:6\\\\=\frac{4}{1}\\\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{a}{1}=a\\\\=4$

$\frac{4}{5}\cdot \:15\\\\\mathrm{Convertir\:a\:fraccion}:\quad \:15=\frac{15}{1}\\\\=\frac{4}{5}\cdot \frac{15}{1}\\\\Cancelar:5\\\\=\frac{4}{1}\cdot \frac{3}{1}\\\mathrm{Multiplicar\:fracciones}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}\\\\=\frac{4\cdot \:3}{1\cdot \:1}\\\\=\frac{12}{1}\\\\\mathrm{Aplicar\:la\:regla}\:\frac{a}{1}=a\\\\=12$

$\frac{2}{3}\cdot \:15\\\\\mathrm{Convertir\:a\:fraccion}:\quad \:15=\frac{15}{1}\\\\=\frac{2}{3}\cdot \frac{15}{1}\\\\Cancelar:3\\\\=\frac{2}{1}\cdot \frac{5}{1}\\\\\mathrm{Multiplicar\:fracciones}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}\\\\=\frac{2\cdot \:5}{1\cdot \:1}\\\\=\frac{10}{1}\\\\\mathrm{Aplicar\:la\:regla}\:\frac{a}{1}=a\\\\=10$

$\frac{3}{7}\cdot \:21\\\\\mathrm{Convertir\:a\:fraccion}:\quad \:21=\frac{21}{1}\\\\=\frac{3}{7}\cdot \frac{21}{1}\\\\Cancelar:7\\\\=\frac{3}{1}\cdot \frac{3}{1}\\\\\mathrm{Multiplicar\:fracciones}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}\\\\=\frac{3\cdot \:3}{1\cdot \:1}\\\\=\frac{9}{1}\\\\\mathrm{Aplicar\:la\:regla}\:\frac{a}{1}=a\\\\=9$

$\frac{4}{5}\cdot \:20\\\\\mathrm{Convertir\:a\:fraccion}:\quad \:20=\frac{20}{1}}\\\\=\frac{4}{5}\cdot \frac{20}{1}\\\\Cancelar:5\\\\=\frac{4}{1}\cdot \frac{4}{1}\\\\\mathrm{Multiplicar\:fracciones}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}\\\\=\frac{4\cdot \:4}{1\cdot \:1}\\\\=\frac{16}{1}\\\\\mathrm{Aplicar\:la\:regla}\:\frac{a}{1}=a\\\\=16$

$\frac{1}{4}\cdot \:12\\\\\mathrm{Convertir\:a\:fraccion}:\quad \:12=\frac{12}{1}\\\\=\frac{1}{4}\cdot \frac{12}{1}\\\\Cancelar:4\\\\=\frac{3}{1}\\\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{a}{1}=a\\\\=3$
