Answer 1

$a) \frac{3}{5} *\frac{7}{6} = \frac{3 * 7}{5 * 6} = \frac{21}{30} =\boxed{ \frac{7}{10} }\\\\b) \frac{2}{5} * \frac{7}{9} = \frac{2 * 7}{5 * 9} = \boxed{\frac{14}{45} }\\\\c) \frac{28}{7} \div{} \frac{4}{5} = \frac{28}{7} * \frac{5}{4} = \frac{140}{28} =\frac{70}{14} = \frac{35}{7} = \frac{7}{1} = \boxed{7}$
