Приведите дроби:
а) $\frac{1}{4}, \frac{7}{6}, \frac{3}{8}, \frac{17}{12}$ к знаменателю 24;
б) $\frac{2}{3}, \frac{7}{5}, \frac{4}{9}, \frac{16}{15}$ к знаменателю 90;
в) $\frac{5}{12}, \frac{7}{9}, \frac{5}{6}, \frac{4}{4}$ к знаменателю 36;
г) $\frac{3}{5}, \frac{3}{4}, \frac{8}{25}, \frac{7}{50}$ к знаменателю 100.
$\frac{1}{4} = \frac{1 * 6}{4 * 6} = \frac{6}{24}$;
$\frac{7}{6} = \frac{7 * 4}{6 * 4} = \frac{28}{24}$;
$\frac{3}{8} = \frac{3 * 3}{8 * 3} = \frac{9}{24}$;
$\frac{17}{12} = \frac{17 * 2}{12 * 2} = \frac{34}{24}$.
$\frac{2}{3} = \frac{2 * 30}{3 * 30} = \frac{60}{90}$;
$\frac{7}{5} = \frac{7 * 18}{5 * 18} = \frac{126}{90}$;
$\frac{4}{9} = \frac{4 * 10}{9 * 10} = \frac{40}{90}$;
$\frac{16}{15} = \frac{16 * 6}{15 * 6} = \frac{96}{90}$.
$\frac{5}{12} = \frac{5 * 3}{12 * 3} = \frac{15}{36}$;
$\frac{7}{9} = \frac{7 * 4}{9 * 4} = \frac{28}{36}$;
$\frac{5}{6} = \frac{5 * 6}{6 * 6} = \frac{30}{36}$;
$\frac{4}{4} = \frac{4 * 9}{4 * 9} = \frac{36}{36}$.
$\frac{3}{5} = \frac{3 * 20}{5 * 20} = \frac{60}{100}$;
$\frac{3}{4} = \frac{3 * 25}{4 * 25} = \frac{75}{100}$;
$\frac{8}{25} = \frac{8 * 4}{25 * 4} = \frac{32}{100}$;
$\frac{7}{50} = \frac{7 * 2}{50 * 2} = \frac{14}{100}$.
