Answer 1

$Boa \: \: noite!!! \\ \\ \frac{2}{5} \times {( - \frac{1}{4} })^{2} - \frac{1}{8} \\ \frac{2}{5} \times \frac{1}{16} - \frac{1}{8} \\ \frac{1}{5} \times \frac{1}{8} - \frac{1}{8} \\ \frac{1}{40} - \frac{1}{8} \\ \frac{1 - 5}{40} = - \frac{ {4}^{ + \div 4} }{ {40}^{ \div 4} } = - \frac{1}{10} \\ \\ Espero \: \: ter \: \: ajudado!:)$
