Ответ:
- а) \(\frac{2}{9}+\frac{3}{7}=\frac{14}{63}+\frac{27}{63}=\frac{41}{63}\).
- б) \(\frac{7}{8}+\frac{3}{4}=\frac{7}{8}+\frac{6}{8}=\frac{13}{8}=1\frac{5}{8}\).
- в) \(\frac{5}{24}+\frac{23}{30}=\frac{25}{120}+\frac{92}{120}=\frac{117}{120}=\frac{39}{40}\).
- г) \(\frac{59}{60}+\frac{39}{40}=\frac{118}{120}+\frac{117}{120}=\frac{235}{120}=\frac{47}{24}=1\frac{23}{24}\).
- д) \(3\frac{1}{8}+2\frac{1}{7}=5+\frac{7}{56}+\frac{8}{56}=5\frac{15}{56}\).
- е) \(5\frac{1}{6}+1\frac{2}{3}=6+\frac{1}{6}+\frac{4}{6}=6\frac{5}{6}\).
