Espero ter ajudado!

Answer 2

$a) \frac{1}{5} \times \frac{4}{7} = \frac{4}{35}$

$b) \frac{4}{9} \times \frac{7}{5} = \frac{28}{45}$

$c) \frac{6}{6} \times \frac{2}{6} = \frac{12}{36} = \frac{1}{3}$

$d) \frac{2}{9} \times \frac{2}{9} = \frac{4}{81}$

$e) \frac{2}{4} \times \frac{3}{7} = \frac{6}{28} = \frac{3}{14}$
