:-)

Explicación paso a paso:

1)

$\frac{2}{6}+\frac{1}{4}\\\\\frac{4\ x\ 2\ +\ 6\ x\ 1}{6\ x\ 4} = \frac{8+ 6}{24} =\frac{14}{24} = \frac{7}{12}$

2)

$\frac{9}{4}-\frac{2}{4} = \frac{7}{4}$

3)

$\frac{3}{4}-\frac{1}{12}\\\\\frac{12\ x\ 3\ -\ 4\ x\ 1}{4\ x\ 12} = \frac{36 - 4}{48} = \frac{32}{48} = \frac{2}{3}$

4)

$\frac{6}{8}\ x \frac{7}{9}\\\\\frac{6\ x\ 7}{8\ x\ 9} = \frac{42}{72} = \frac{7}{12}$

5)

$\frac{3}{5}\ x \frac{2}{9}\\\\\frac{3\ x\ 2}{5\ x\ 9} = \frac{6}{45} = \frac{2}{15}$

6)

$\frac{12}{9}\div \frac{6}{8}\\\\\frac{12}{9}\times \frac{8}{6} =\frac{12\ x\ 8}{9\ x\ 6} = \frac{96}{54}= \frac{16}{9}$

7)

$\frac{5}{6}\div \frac{3}{4}\\\\\frac{5}{6}\times \frac{4}{3}= \frac{5\ x\ 4}{6\ x\ 3} = \frac{20}{18} = \frac{10}{9}$
