Qual cálculo dessa pergunta

Answer 1

$3 \div \frac{7}{2} - \frac{10}{8} +\frac{1}{6} = \\ 3. \frac{2}{7} - \frac{5}{4} + \frac{1}{6} \\ = \frac{6}{7} - \frac{5}{4} + \frac{1}{6} = \frac{72 - 210 + 14}{84}$

$- \frac{124}{84} = - \frac{31}{21}$

Answer 2

- 3 × 2 / 7 - 10 / 8 + 1 / 6

- 6 / 7 - 10 / 8 + 1 / 6

( - 144 - 210 + 28 ) / 168

( - 354 + 28 ) / 168

- 326 / 168 ( simplificar )

- 163 / 84
