Expressões e problemas com racionais

Oi filha,

Antes de resolver os exercícios seguintes, recorde a precedência de operadores.

Agora calcule as seguintes expressões:

  1. [\frac{1}{2} \times (\frac{1}{3} + \frac{4}{6})] =
  2. \frac{1}{5} + \{[\frac{4}{9} \div (\frac{1}{2} \times \frac{2}{4} - \frac{1}{9})]\} =
  3. (4 - \frac{4}{5}) \div (9 + \frac{1}{3}) =
  4. \{4 + 2 \times [32 - \frac{1}{4} \times (\frac{1}{3} - \frac{1}{5}) + 2] + 16\} + 1 =
  5. \frac{\frac{4}{5} \div (\frac{7}{3} - 1)}{\frac{7}{9} - 3} = [\frac{4}{5} \div (\frac{7}{3} - 1)] \div (\frac{7}{9} - 3) =
  6. [4\frac{1}{3} + \frac{2}{7} \times (3\frac{4}{5} - 2\frac{2}{3})] \div (\frac{3}{5} \times \frac{6}{5})=

E resolva os seguintes problemas.

Beijo do pai!
