​

Answer 1

Resposta:

$\boxed{ \frac{43}{12} }$

Explicação passo-a-passo:

$\frac{9}{2} - \frac{1}{4} - \frac{2}{3}$

$\frac{9 \times 6}{2 \times 6} - \frac{1 \times 3}{4 \times 3} - \frac{2 \times 4}{3\times 4}$

$\frac{54}{12} - \frac{3}{12} - \frac{8}{12}$

$\frac{54 - 3 - 8}{12}$

$\boxed{ \frac{43}{12} }$
