Answer 1

Respuesta:

             $\frac{-427}{90}$

Explicación paso a paso:

$-3 + 1\frac{1}{3} - [ \frac{4}{3} -(\frac{5}{9} +\frac{1}{5} )] -2\frac{1}{2 } =$

$-3+\frac{1*3+1}{3} -[\frac{4}{3} -(\frac{25+9}{45} )] -\frac{2*2+1}{2} =$

$-3+\frac{4}{3} -[\frac{4}{3} -\frac{34}{45} ]-\frac{5}{2} =$

$-3+\frac{4}{3} -[ \frac{60-34}{45} ]-\frac{5}{2} =$

$-3+\frac{4}{3} -\frac{26}{45} -\frac{5}{2} =$

$\frac{-270+120-52-225}{90} = \frac{-427}{90}$
