Question

Para cada item escreva duas frações equivalentes 8/20 16/36 21/9 42/12 20/30 31/28

Answer 1

$\frac{8}{20} = \frac{4}{10} = \frac{2}{5}$
$\frac{16}{36} = \frac{8}{18} = \frac{4}{9}$
$\frac{21}{9} =\frac{14}{6} = \frac{7}{3}$
$\frac{42}{12} = \frac{21}{6} = \frac{7}{2}$
$\frac{20}{30} = \frac{10}{15} = \frac{2}{3}$
$\frac{31}{28} = \frac{62}{56} = \frac{93}{84}$
