Explicação passo-a-passo:
[tex] \frac{2}{6} - \frac{6}{5} \times \frac{1}{3} \div \frac{2}{4} = \\ \\ \frac{1}{3} - \frac{6}{5} \times \frac{1}{3} \div \frac{1}{2} = \\ \\ \frac{1}{3} - \frac{6}{15} \div \frac{1}{2} = \\ \\ \frac{1}{3} - \frac{6}{15} \times 2 = \\ \\ \frac{1}{3} - \frac{12}{15} = \\ \\ \frac{5 - 12}{15} = - \frac{7}{15} [/tex]
