Приводим дроби к общему знаменателю, выполняем вычитание и сокращаем результат, если возможно.

1. \(\frac{4}{5}-\frac{6}{10}=\frac{8}{10}-\frac{6}{10}=\frac{2}{10}=\frac{1}{5}\).
2. \(\frac{4}{17}-\frac{2}{51}=\frac{12}{51}-\frac{2}{51}=\frac{10}{51}\).
3. \(\frac{5}{6}-\frac{4}{9}=\frac{15}{18}-\frac{8}{18}=\frac{7}{18}\).
4. \(\frac{14}{15}-\frac{2}{3}=\frac{14}{15}-\frac{10}{15}=\frac{4}{15}\).
5. \(\frac{4}{25}-\frac{6}{75}=\frac{12}{75}-\frac{6}{75}=\frac{6}{75}=\frac{2}{25}\).
6. \(\frac{26}{45}-\frac{16}{30}=\frac{52}{90}-\frac{48}{90}=\frac{4}{90}=\frac{2}{45}\).
7. \(\frac{13}{18}-\frac{5}{24}=\frac{52}{72}-\frac{15}{72}=\frac{37}{72}\).
8. \(\frac{15}{27}-\frac{1}{9}=\frac{5}{9}-\frac{1}{9}=\frac{4}{9}\).
9. \(\frac{13}{18}-\frac{5}{24}=\frac{52}{72}-\frac{15}{72}=\frac{37}{72}\).
10. \(\frac{5}{13}-\frac{7}{26}=\frac{10}{26}-\frac{7}{26}=\frac{3}{26}\).
