Respuesta:

1. Resolver

* $\frac{2}{8}+\frac{15}{4}=\frac{1+15}{4}=\frac{16}{4}=4$

* $\frac{1}{4}+\frac{2}{3}+\frac{4}{5}=\frac{15}{60}+\frac{40}{60}+\frac{48}{60}=\frac{15+40+48}{60}=\frac{103}{60}$

* $\frac{8}{5}\cdot \frac{16}{40}=\frac{8}{5}\cdot \frac{2}{5}=\frac{8\cdot \:2}{5\cdot \:5}=\frac{16}{25}$

* $\frac{12}{18}\cdot \frac{10}{4}\cdot \frac{9}{15}=\frac{2}{3}\cdot \frac{10}{4}\cdot \frac{9}{15}=\frac{5}{3}\cdot \frac{9}{15}=\frac{5}{3}\cdot \frac{3}{5}=1$

* $\frac{5}{9}\cdot \frac{3}{15}\cdot \frac{18}{20}=\frac{5}{9}\cdot \frac{1}{5}\cdot \frac{18}{20}=\frac{1}{9}\cdot \frac{18}{20}=\frac{1}{9}\cdot \frac{9}{10}=\frac{1}{10}$
