Answer 1

Respuesta:

1. $\frac{9}{5} = 1 \frac{4}{5}$
2. $\frac{16}{2} = 8$
3. $\frac{8}{3} = 2 \frac{2}{3}$
4. $\frac{ - 1}{4}$
5. $\frac{1}{5} + \frac{1}{2} = \frac{5}{10} + \frac{2}{10} = \frac{7}{10}$
6. $\frac{6}{4} - \frac{2}{3} = \frac{18}{12} - \frac{8}{12} = \frac{10}{12} = \frac{5}{6}$
7. $\frac{2}{5} + \frac{5}{2} + \frac{3}{10} =$si le sacamos equivalencia es igual a
8. $\frac{4}{10} + \frac{25}{10} + \frac{3}{10} = \frac{32}{10} = 3 \frac{2}{10}$
9. $\frac{1}{3} - \frac{5}{2} = \frac{2}{6} - \frac{15}{6} = \frac{ - 13}{6} \\ \frac{ - 13}{6} - \frac{4}{8} = \frac{ - 104}{48} - \frac{24}{48} = \frac{ - 80}{48}$
