Ответ:
\[\frac{3}{5}+\frac{3}{2}=\frac{6}{10}+\frac{15}{10}=\frac{21}{10}.\]
\[\frac{7}{5}:\frac{21}{10}=\frac{7}{5}\cdot\frac{10}{21}=\frac{2}{3}.\]
Ответ: \(\frac{2}{3}\).
\[\frac{3}{5}+\frac{3}{2}=\frac{6}{10}+\frac{15}{10}=\frac{21}{10}.\]
\[\frac{7}{5}:\frac{21}{10}=\frac{7}{5}\cdot\frac{10}{21}=\frac{2}{3}.\]
