Explicación paso a paso:
1. [tex]\frac{8}{3} +\frac{5}{3} - \frac{1}{2} \\\frac{13}{3}-\frac{1}{2}\\\frac{26}{6}-\frac{3}{6} \\\frac{26-3}{6} \\\frac{23}{6}[/tex] 2. [tex]\frac{6}{4}+\frac{2}{3}\cdot \frac{5}{4}\\\frac{6}{4}+\frac{5}{6}\\\frac{3}{2}+\frac{5}{6}\\\frac{9}{6}+\frac{5}{6}\\\frac{9+5}{6}\\\frac{14}{6}\\\frac{7}{3}[/tex]
3.[tex]\frac{2}{5}+\frac{2}{4}\cdot \frac{9}{3}\\\frac{2}{5}+\frac{3}{2}\\\frac{4}{10}+\frac{15}{10}\\\frac{4+15}{10}\\\frac{19}{10}[/tex] 4. [tex]\frac{2}{7}+\frac{9}{3}\cdot \frac{2}{6}\\\frac{2}{7}+1\\\frac{2}{7}+\frac{7}{7}\\\frac{2+7}{7}\\\frac{9}{7}[/tex]
5. [tex]\frac{2}{6}+\frac{4}{5}\cdot \frac{2}{4}\\\frac{2}{6}+\frac{2}{5}\\\frac{1}{3}+\frac{2}{5}\\\frac{5}{15}+\frac{6}{15}\\\frac{5+6}{15}\\\frac{11}{15}[/tex]
