Answer 1

Respuesta:

1. $\frac{1}{5 } + \frac{3}{4} = \frac{4 + 15}{20} = \frac{19}{20}$
2. $\frac{2}{3} + \frac{3}{5} = \frac{10 + 9}{15} = \frac{19}{15}$
3. $\frac{3}{2} - \frac{4}{6} = \frac{18 - 8}{12} = \frac{10}{12}$
4. $\frac{3}{2} - \frac{7}{5} = \frac{15 - 14}{10} = \frac{1}{10}$
5. $\frac{3}{4} + \frac{5}{2} = \frac{6 + 20}{8} = \frac{26}{8}$
6. $\frac{3}{2} + \frac{4}{7} = \frac{21 + 8}{14} = \frac{29}{14}$
