Ответ:
- \(\frac{3}{4}-\frac{5}{14}=\frac{21}{28}-\frac{10}{28}=\frac{11}{28}\).
- \(\frac{7}{16}-\frac{1}{24}=\frac{21}{48}-\frac{2}{48}=\frac{19}{48}\).
- \(\frac{6}{7}-\frac{3}{4}=\frac{24}{28}-\frac{21}{28}=\frac{3}{28}\).
- \(\frac{3}{4}-\frac{2}{25}=\frac{75}{100}-\frac{8}{100}=\frac{67}{100}\).
- \(\frac{11}{18}-\frac{13}{20}=\frac{110}{180}-\frac{117}{180}=-\frac{7}{180}\).
- \(\frac{7}{12}-\frac{9}{20}=\frac{35}{60}-\frac{27}{60}=\frac{8}{60}=\frac{2}{15}\).
Ответ: а) \(\frac{11}{28}\); б) \(\frac{19}{48}\); в) \(\frac{3}{28}\); г) \(\frac{67}{100}\); д) \(-\frac{7}{180}\); е) \(\frac{2}{15}\).
