Answer 5

\(a.\left(131,4-80,8\right):2,3+21,84.2\)

\(=50,6:2,3+43,68\)

\(=22+43,68=65,68\)

\(b.8,16:\left(1,32+3,48\right)-0,345:2\)

\(=8,16:4,8-0,345:2\)

\(=1,7-0,1725=1,5275\)

Answer 6

a){131,4-80,8}:2,3+21,84.2

=50,6:2,3+21,84.2

=22+43,68

=66,68.

b)8,16:{1,32+3,48}-0,345:2

=8,16:4,8-0,1725

=1,7-0,1725

=1,5275.
