Выполните действия: а) \(\frac{11}{18}+\frac{5}{12}\); б) \(2\frac{1}{8}+3\frac{3}{16}\); в) \(\frac{3}{4}+\frac{5}{7}\); г) \(4\frac{7}{25}+2\frac{4}{10}\); д) \(\frac{5}{12}+5\frac{2}{21}\); е) \(1\frac{11}{18}+\frac{7}{15}\).
- \(\frac{11}{18}+\frac{5}{12}=\frac{22}{36}+\frac{15}{36}=\frac{37}{36}=1\frac{1}{36}\).
- \(2\frac{1}{8}+3\frac{3}{16}=2\frac{2}{16}+3\frac{3}{16}=5\frac{5}{16}\).
- \(\frac{3}{4}+\frac{5}{7}=\frac{21}{28}+\frac{20}{28}=\frac{41}{28}=1\frac{13}{28}\).
- \(4\frac{7}{25}+2\frac{4}{10}=4\frac{7}{25}+2\frac{2}{5}=4\frac{14}{50}+2\frac{20}{50}=6\frac{34}{50}=6\frac{17}{25}\).
- \(\frac{5}{12}+5\frac{2}{21}=5+\frac{35}{84}+\frac{8}{84}=5\frac{43}{84}\).
- \(1\frac{11}{18}+\frac{7}{15}=1+\frac{55}{90}+\frac{42}{90}=1\frac{97}{90}=2\frac{7}{90}\).
