Question

o resultado da expressão abaixo é

Answer 1

Resposta:

$- \frac{35}{12}$

Explicação passo-a-passo:

$( \frac{2}{3} - \frac{1}{3} \times \frac{7}{4} ) + ( \frac{1}{2} - \frac{3}{2} \times \frac{7}{ 3} )$

$( \frac{2}{3} - \frac{7}{12} ) + ( \frac{1}{2} - \frac{3}{2} \times \frac{7}{3} )$

$( \frac{2}{3} - \frac{7}{12} ) + ( \frac{1}{2} - \frac{1}{2} \times 7)$

$\frac{1}{12} + ( \frac{1}{2} - \frac{1}{2} \times 7)$

$\frac{1}{12} + ( \frac{1}{2} - \frac{7}{2} )$

$\frac{1}{12} + ( - 3)$

$\frac{1}{12} - 3$

$- \frac{35}{12}$
