Вычислите: 4/25 + 15/4; 9/4 + 8/5; 14/25 + 3/2; 11/4 + 6/5; 3/4 + 7/25.

1. \(\frac{4}{25}+\frac{15}{4}=\frac{16}{100}+\frac{375}{100}=\frac{391}{100}\).
2. \(\frac{9}{4}+\frac{8}{5}=\frac{45}{20}+\frac{32}{20}=\frac{77}{20}\).
3. \(\frac{14}{25}+\frac{3}{2}=\frac{28}{50}+\frac{75}{50}=\frac{103}{50}\).
4. \(\frac{11}{4}+\frac{6}{5}=\frac{55}{20}+\frac{24}{20}=\frac{79}{20}\).
5. \(\frac{3}{4}+\frac{7}{25}=\frac{75}{100}+\frac{28}{100}=\frac{103}{100}\).

Ответ: \(\frac{391}{100};\ \frac{77}{20};\ \frac{103}{50};\ \frac{79}{20};\ \frac{103}{100}\).
