Question

resolver 0,5 + 1/3 × 1/2 - 0,4 ÷ √1/9 =​

Answer 1

$0.5 + \frac{1}{3} \times \frac{1}{2} - 0.4 \div \sqrt{ \frac{1}{9} } = \\ \frac{5}{10} + \frac{1}{3} \times \frac{1}{2} - \frac{4}{10} \div \sqrt{ \frac{ {1}^{2} }{ {3}^{2} } } = \\ \frac{1}{2} + \frac{1}{3} \times \frac{1}{2} - \frac{2}{5} \div \frac{1}{3 } = \\ \frac{1}{2} + \frac{1}{3} \times \frac{1}{2} - \frac{2}{5} \times 3 = \\ \frac{1}{2} + \frac{1}{6} - \frac{6}{5} = \\ \frac{15}{30} + \frac{5}{30} - \frac{36}{30} = \\ \frac{15 + 5 - 36}{30} = \\ - \frac{16}{30} = \\ - \frac{8}{15}$
