Пояснение.
Решение.
\[\textbf{а)}\ \frac{5}{6} \cdot 3 = \frac{5 \cdot 3}{6} = \frac{5}{2} = 2\frac{1}{2}\]
\[\textbf{б)}\ \frac{16}{21} \cdot 14 = \frac{16 \cdot 14}{21} = \frac{16 \cdot 2}{3} =\]
\[= \frac{32}{3} = 10\frac{2}{3}\]
\[\textbf{в)}\ \frac{1}{2} \cdot 50 = \frac{1 \cdot 50}{2} = 25\]
\[\textbf{г)}\ 13 \cdot \frac{8}{13} = \frac{13 \cdot 8}{13} = 8\]
\[\textbf{д)}\ 1 \cdot \frac{4}{5} = \frac{4}{5}\]
\[\textbf{е)}\ \frac{11}{15} \cdot 0 = 0\]
