Answer 1

Respuesta:

$\frac{37}{30},$$\frac{14}{15},$$\frac{45}{56},$$\frac{35}{18}$

Explicación paso a paso:

$\frac{4}{8}+\frac{3}{9}+\frac{2}{5}\\\\\frac{1}{2}+\frac{3}{9}+\frac{2}{5}\\\\\frac{1}{2}+\frac{1}{3}+\frac{2}{5}\\\\\frac{15}{30}+\frac{10}{30}+\frac{12}{30}\\\\\frac{15+10+12}{30}\\\\\frac{37}{30}$

$\frac{6}{5}-\frac{2}{3}+\frac{2}{5}\\\\\frac{8}{5}-\frac{2}{3}\\\\\frac{24}{15}-\frac{10}{15}\\\\\frac{24-10}{15}\\\\\frac{14}{15}$

$\frac{3}{7}\times \frac{9}{3}\times \frac{5}{8}\\\\\frac{9}{7}\times \frac{5}{8}\\\\\frac{9\times \:5}{7\times \:8}\\\\\frac{45}{7\times \:8}\\\\\frac{45}{56}$

$\frac{4}{6}\div \frac{2}{5}\div \frac{6}{7}\\\\\frac{4}{6}\times \frac{5}{2}\div \frac{6}{7}\\\\\frac{4}{6}\times \frac{5}{2}\times \frac{7}{6}\\\\\frac{2}{3}\times \frac{5}{2}\times \frac{7}{6}\\\\\frac{2\times \:5\times \:7}{3\times \:2\times \:6}\\\\\frac{5\times \:7}{3\times \:6}\\\\\frac{35}{3\times \:6}\\\\\frac{35}{18}$
