1. Сократите дроби: 5/10, 8/32, 25/40; 7/28; 24/56; 18/81; 300/450.

1. \(\frac{5}{10}=\frac{5:5}{10:5}=\frac{1}{2}\).
2. \(\frac{8}{32}=\frac{8:8}{32:8}=\frac{1}{4}\).
3. \(\frac{25}{40}=\frac{25:5}{40:5}=\frac{5}{8}\).
4. \(\frac{7}{28}=\frac{7:7}{28:7}=\frac{1}{4}\).
5. \(\frac{24}{56}=\frac{24:8}{56:8}=\frac{3}{7}\).
6. \(\frac{18}{81}=\frac{18:9}{81:9}=\frac{2}{9}\).
7. \(\frac{300}{450}=\frac{300:150}{450:150}=\frac{2}{3}\).

Ответ: \(\frac12,\frac14,\frac58;\frac14;\frac37;\frac29;\frac23\).
