32. Вычислите: а) \(\frac{11}{25}+\frac{4}{10}\); б) \(\frac{7}{34}+\frac{1}{17}\); в) \(\frac{13}{20}+\frac{17}{30}\); г) \(\frac{15}{28}+\frac{25}{42}\).

1. а) \(\frac{11}{25}+\frac{4}{10}=\frac{22}{50}+\frac{20}{50}=\frac{42}{50}=\frac{21}{25}\).
2. б) \(\frac{7}{34}+\frac{1}{17}=\frac{7}{34}+\frac{2}{34}=\frac{9}{34}\).
3. в) \(\frac{13}{20}+\frac{17}{30}=\frac{39}{60}+\frac{34}{60}=\frac{73}{60}=1\frac{13}{60}\).
4. г) \(\frac{15}{28}+\frac{25}{42}=\frac{45}{84}+\frac{50}{84}=\frac{95}{84}=1\frac{11}{84}\).

Ответ: а) \(\frac{21}{25}\); б) \(\frac{9}{34}\); в) \(1\frac{13}{60}\); г) \(1\frac{11}{84}\).
