Answer 2

Resposta:

$\sf{segue \: abaixo \: a \: resposta}$

Explicação passo-a-passo:

$\sf{-3-[½-(0,1+¼)]}$

$\sf{ - 3 - ( \frac{1}{2} - ( \frac{1}{10} + \frac{1}{4})) }$

$\sf{ - 3 - ( \frac{1}{2} - \frac{7}{20} )}$

$\sf{ \frac{1}{2} - \frac{7}{20} = \frac{3}{20} }$

$\sf{ - 3 - \frac{3}{20} }$

$\boxed{\boxed{\sf{ - \frac{63}{20} }}}$
