pfvr me ajudem

Answer 1

Olá! td bem?

vamos lá

$\frac{3}{4} + \frac{5}{3} \\ \\ \frac{3}{4} (3) + \frac{5}{3} (4) \\ \\ \frac{9}{12} + \frac{20}{12} \\ \\ \frac{29}{12} \\ \\ \\ \frac{1}{6} + \frac{1}{8} + \frac{1}{10} \\ \\ \frac{1}{6} + \frac{1}{8} (10) + \frac{1}{10} (8) \\ \\ \frac{1}{6} + \frac{10}{80} + \frac{8}{80} \\ \\ \frac{1}{6} + \frac{18}{80} \\ \\ \frac{1}{6} (80) + \frac{18}{80} (6) \\ \\ \frac{80}{480} + \frac{18}{480} \\ \\ \frac{98}{480} \\ \\ \\ \frac{6}{9} - \frac{2}{4} \\ \\ \frac{6}{9} (4) - \frac{2}{4} (9) \\ \\ \frac{24}{36} - \frac{18}{36} \\ \\ \frac{6}{36} \\ \\ \\ \frac{12}{5} \times \frac{7}{8} \\ \\ \frac{12}{5} (8) \times \frac{7}{8} (5) \\ \\ \frac{96}{40} \times \frac{35}{40} \\ \\ \frac{3360}{40} \\ \\ \frac{3360}{40} \div \frac{20}{20} \\ \\ \frac{168}{2} \\ \\ \\ \frac{8}{3} \div \frac{4}{6} \\ \\ \frac{8}{3} (6) \div \frac{4}{6} (3) \\ \\ \frac{108}{18} \div \frac{12}{18} \\ \\ \frac{9}{18}$
