Answer 1

Answer:9/2 - [1/5 +{1/4 +{5/6- 1/3 + 1/2}]

=4.5 - {0.20 + [0.25 +{5/6 - 2/6 + 3/6}

=4.5 - {0.20 +[0.25 +{1}]

=4.5 - {1.45}

=3.05

Hope the answer was helpful.

Answer 2

=> $\frac{9}{20} - [ { \frac{1}{6} +[ { \frac{1}{4} + ( \frac{5}{6} - \frac{1}{3} + \frac{1}{2})] } ]$   => $\frac{9}{20} - [ { \frac{1}{6} +[ { \frac{1}{4} + ( \frac{5 - 2 + 3}{6} )] } ]$

=> $\frac{9}{20} - [ { \frac{1}{6} +[ { \frac{1}{4} + \frac{6}{6} ] } ]$      => $\frac{9}{20} - [ { \frac{1}{6} +[ { \frac{1}{4} + 1\\ ] } ]$

=> $\frac{9}{20} - [ { \frac{1}{6} +[ { \frac{1+4}{4} \\ ] } ]$    => $\frac{9}{20} - [ { \frac{1}{6} +[ { \frac{5}{4} ] } ]$    => $\frac{9}{20} - [ { \frac{4 + 30}{6} ] }$   => $\frac{9}{20} - \frac{34}{6}$   => $\frac{9}{20} - \frac{17}{3}$

=> $\frac{27 -340}{60}$ =>   $\frac{-313}{60}$
