Question

quanto é? Gente me respondem por favor ​

Answer 1

$f)( + 3) \times ( - \frac{3}{9} ) \times ( \frac{18}{6} ) \\ - 3 \times \frac{1}{3} \times 3 \\ - 3$

$e)( - \frac{1}{9} ) \times ( - \frac{3}{18}) \\ \frac{1}{9} \times \frac{1}{6} \\ \frac{1}{54}$

$g)( - \frac{4}{9} ) \div ( + \frac{16}{81} ) \\ - \frac{4}{9} \times \frac{81}{16} \\ - \frac{9}{4}$
