Ответ:
а) \(\frac{15}{24} + \frac{3}{8} = \frac{5}{8} + \frac{3}{8} = 1\).
б) \(\frac{3}{5} − \frac{13}{45} = \frac{27}{45} − \frac{13}{45} = \frac{14}{45}\).
в) \(\frac{15}{16} : \frac{10}{24} = \frac{15}{16} · \frac{24}{10} = \frac{9}{4} = 2\frac{1}{4}\).
г) \(\frac{25}{24} · \frac{3}{5} = \frac{5}{8}\).
