Answer 2

Resposta:

$\frac{-3}{4}+\frac{\frac{-1}{2} }{\frac{1}{4} }=\frac{-11}{4}ou -2,75$

Explicação passo-a-passo:

$\frac{-3}{4} +\frac{\frac{-1}{2} }{\frac{1}{4} } = \frac{-3}{4} + \frac{-1*4}{2*1}=\frac{-3}{4}  + \frac{-4}{2}=\frac{-3}{4} +\frac{-2}{1} =\frac{-3+4*-2}{4}=\frac{-3-8}{4}=\frac{-11}{4}$ ou de forma decimal -2,75
