Answer 1

$\frac{2}{3} \times \frac{4}{5} = \frac{8}{15}$
$\frac{8}{4} - \frac{4}{4} = \frac{4}{4} = 1$
$\frac{5}{7} + \frac{8}{7} = \frac{13}{7}$
$\frac{7}{3} \div \frac{6}{7} = \frac{7}{3} \times \frac{7}{6} = \frac{49}{18}$
$\frac{10}{1} + \frac{9}{1} = 10 + 9 = 19$
$\frac{27}{3} - \frac{13}{3} = \frac{14}{3}$
$\frac{5}{6} + \frac{4}{6} = \frac{9}{6}$
$\frac{9}{3} \div \frac{6}{4 } = \frac{9}{3 } \times \frac{4}{6} = (simplificam) \\ = \frac{3 \times 4}{3 \times 2} = 1$
$\frac{2}{6} = 2$
$\frac{7}{6} + \frac{3}{6} = \frac{10}{6}$
$\frac{10}{10} - \frac{9}{10 } = \frac{1}{10}$
