Answer 1

boa tarde !!!!

$( \frac{1}{3} + \frac{1}{4} ) \div \frac{5}{2} + \frac{2}{3} \\ \\ \frac{7}{12} \times \frac{2}{5} + \frac{2}{3} \\ \\ \frac{7}{6} \times \frac{1}{5} + \frac{2}{3} \\ \\ \frac{7}{30} + \frac{2}{3} \\ \\ \frac{9}{10} \\ \\ = 0,9 \\ \\ \\ ( \frac{3}{4} + \frac{1}{4} - \frac{1}{2} ) \div \frac{3}{2} \\ \\ \frac{1}{2} \times \frac{2}{3} \\ \\ \frac{1}{3} \\ \\ = 0,333333,3 {}^{ - 1}$

espero que eu tenha conseguido te ajudar...
