Vamos resolver cada expressão numérica:

A.


B.


C.


D.
\[
120-5.7:\{ 3+16:8+[7.3+(5.2-1)]\} = 120-5.7:\{ 3+16:8+[7.3+4.2]\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\} = 120-5.7:\{ 3+16:8+11.5\
