Answer 1

$\frac{2}{7} \times 6 = 1 \\ \frac{4}{5} \times \frac{3}{8} = \frac{3}{10} \\ \frac{7}{11} \times \frac{3}{4} = \frac{21}{44} \\ \frac{3}{22} \times \frac{5}{6} = \frac{5}{44} \\ ( \frac{5}{7} + \frac{2}{7} ) - \frac{6}{8} = \frac{1}{4} \\ ( \frac{7}{9} + \frac{5}{9} ) - \frac{4}{8} = \frac{5}{6}$
