Раскройте скобки:
1) $14 * (\frac{1}{2}m + \frac{3}{7}n)$;
2) $\frac{1}{6} * (\frac{12}{17}b - \frac{18}{23}c)$;
3) $8 * (\frac{1}{4}p - \frac{5}{24}q + \frac{7}{12}t)$;
4) $1\frac{3}{4} * (4a + \frac{16}{21}b - 2\frac{2}{3})$.
$14 * (\frac{1}{2}m + \frac{3}{7}n) = 14 * \frac{1}{2}m + 14 * \frac{3}{7}n = 7m + 6n$
$\frac{1}{6} * (\frac{12}{17}b - \frac{18}{23}c) = \frac{1}{6} * \frac{12}{17}b - \frac{1}{6} * \frac{18}{23}c = \frac{2}{17}b - \frac{3}{23}c$
$8 * (\frac{1}{4}p - \frac{5}{24}q + \frac{7}{12}t) = 8 * \frac{1}{4}p - 8 * \frac{5}{24}q + 8 * \frac{7}{12}t = 2p - \frac{5}{3}q + \frac{14}{3}t = 2p - 1\frac{2}{3}q + 4\frac{2}{3}t$
$1\frac{3}{4} * (4a + \frac{16}{21}b - 2\frac{2}{3}) = \frac{7}{4} * 4a + \frac{7}{4} * \frac{16}{21}b - \frac{7}{4} * \frac{8}{3} = 7a + \frac{4}{3}b - \frac{14}{3} = 7a + 1\frac{1}{3}b - 4\frac{2}{3}$.
