Respuesta:

Las respuestas respectivamente son: \frac{3}{8} ; -\frac{1}{6} ; -\frac{13}{10} ; -\frac{164}{35}

Explicación paso a paso:

a) - 1 - (-\frac{2}{3} + 1) - [2\frac{1}{4} -(2-\frac{3}{2} )-\frac{2}{6} -\frac{5}{8} ] + 1\frac{3}{2}

- 1 - (\frac{-2(1) + 3}{3}) - [\frac{4(2)+1}{4} -(\frac{2(2)-3}{2} )-(\frac{2}{6} +\frac{5}{8}) ] + 1\frac{3}{2}

- 1 - (\frac{-2 + 3}{3}) - [\frac{8+1}{4} -(\frac{4-3}{2} )-(\frac{2(8)+6(5)}{6(8)} ) ] + \frac{2(1)+3}{2}

- 1 - (\frac{1}{3}) - [\frac{9}{4} -\frac{1}{2} -(\frac{16+30}{48} ) ] + \frac{2+3}{2}

- (1 + \frac{1}{3}) - [\frac{9(2)-4(1)}{4(2)}-(\frac{46}{48} ) ] + \frac{5}{2}

- (1 + \frac{1}{3}) - [\frac{18-4}{8}-(\frac{23}{24} ) ] + \frac{5}{2}

- (\frac{3+1}{3}) - [\frac{14}{8}-\frac{23}{24}  ] + \frac{5}{2}

- \frac{4}{3} - [\frac{14(24)-8(23)}{8(24)} ] + \frac{5}{2}

- \frac{4}{3} - [\frac{336-184}{192} ] + \frac{5}{2}

- \frac{4}{3} - [\frac{152}{192} ] + \frac{5}{2}

- \frac{4}{3} - [\frac{152}{192} ] + \frac{5}{2}

- \frac{4}{3} - \frac{19}{24} + \frac{5}{2}

- (\frac{4}{3} + \frac{19}{24}) + \frac{5}{2}

- (\frac{4(24)+3(19)}{3(24)}) + \frac{5}{2}

- (\frac{96+57}{72}) + \frac{5}{2}

- (\frac{153}{72}) + \frac{5}{2}

- \frac{17}{8} + \frac{5}{2}

\frac{-17(2)+8(5)}{8(2)}

\frac{-34+40}{16}

  \frac{6}{16}

= \frac{3}{8}

b) -[3\frac{2}{4} -2,333333.....] + (-\frac{1}{5}) + 1,2

-[\frac{4(3)+2}{4} -2,333333.....] -\frac{1}{5}+ \frac{6}{5}

-[\frac{12+2}{4} -2,333333.....]+ \frac{6}{5} -\frac{1}{5}

-[\frac{14}{4} -2,333333.....]+ \frac{6-1}{5}

-[\frac{7}{2} -\frac{23-2}{9}]+ \frac{5}{5}

-[\frac{7}{2} -\frac{21}{9}]+ 1

-[\frac{7}{2} -\frac{7}{3}]+ 1

1-[\frac{7(3)-2(7)}{2(3)}]

1-[\frac{21-14}{6}]

1-\frac{7}{6}

\frac{1(6)-7}{6}

\frac{6-7}{6}

-\frac{1}{6}

c) 2\frac{2}{3} -[3,5 - (1 - 0, 6666...)]+1\frac{1}{5} -2

\frac{3(2)+2}{3} -[\frac{7}{2} - (1- \frac{6}{9} )]+\frac{5(1)+1}{5} -2

\frac{8}{3} -[\frac{7}{2} - (\frac{3}{9} )]+\frac{6-5(2)}{5}

\frac{8}{3} -[\frac{7}{2} - \frac{1}{3} ]+\frac{6-10}{5}

\frac{8}{3} -[\frac{7(3)-2(1)}{2(3)} ]+(\frac{-4}{5})

\frac{8}{3} -[\frac{21-2}{6} ]-\frac{4}{5}

[\frac{8}{3} -\frac{19}{6}]-\frac{4}{5}

[\frac{8(6)-3(19)}{3(6)} ]-\frac{4}{5}

[\frac{48-57)}{18} ]-\frac{4}{5}

\frac{-9}{18} -\frac{4}{5}
