Answer 2

Resposta:

$\frac{5}{2} - \frac{1}{4} \times \frac{1}{2} \div \frac{3}{4} = \\ \\ \frac{5}{2} - \frac{1 \times 1}{4 \times 2} \div \frac{3}{4} = \\ \\ \frac{5}{2} - \frac{1}{8} \div \frac{3}{4} = \\ \\ \frac{5}{2} - \frac{1}{8} \times \frac{4}{3} = \\ \\ \frac{5}{2} - \frac{1}{2} \times \frac{1}{3} = \\ \\ \frac{5}{2} - \frac{1}{6} = \\ \\ \frac{3 \times 5 - 1}{6} = \\ \\ \frac{15 - 1}{6} = \\ \\ \frac{14 \div 2}{6 \div 2}= \\ \\ \green{ \dfrac{7}{3} }$
