Answer 2

Resposta:

a) $\frac{-149}{44}$

Explicação passo a passo:

$\frac{6}{11}-1 +(1-\frac{15}{22}) -(3+\frac{1}{4} )=\\\\=\frac{24-44}{44} +\frac{44-30}{44} -(\frac{132+11}{44} )\\\\=\frac{-20}{44} +\frac{14}{44} -(\frac{143}{44} )\\\\=\frac{-20}{44} +\frac{14}{44} -(\frac{143}{44} )\\\\=\frac{-149}{44}$
