Answer 1

Resposta:

$\frac{25}{12}$

Explicação passo-a-passo:

$\frac{3}{4} + \frac{7}{3} - \frac{1}{1} \\ \\ \frac{3}{4} + \frac{7}{3} - 1 \\ \\ \frac{3 \times 3}{4 \times 3} + \frac{7}{3} - 1 \\ \\ \frac{3 \times 3}{4 \times 3} + \frac{7 \times 4}{3 \times 4} - 1 \\ \\ \frac{3 \times 3}{4 \times 3} + \frac{7 \times 4}{3 \times 4} - \frac{1}{1} \\ \\ \frac{9}{12} + \frac{28}{12} - \frac{1 \times 12}{1 \times 12} \\ \\ \frac{9}{12} + \frac{28}{12} - \frac{12}{12} \\ \\ \frac{9 + 28 - 12}{12} \\ \\ 9 + 28 - 12 \\ 37 - 12 \\ 25 \\ \\ \frac{25}{12}$
