Question

media aritmetica a nr a=5/3-3/7 si b=1/3+3/7

Answer 1

[tex]M_a=(a+b)/2\\\\ a=5/3-3/7=\ \textgreater \ a=37/21-9/21=\ \textgreater \ a=1,33.\\\\ b=1/3+3/7=\ \textgreater \ b=7/21+9/21=\ \textgreater \ b=0,76\\\\ M_a=(0,76+1,33)/2=\ \textgreater \ M_a=2.09/2=\ \textgreater \ M_a=1,045.[/tex]

Answer 2

A= (5 + 0 + 7 )  impartit la 3 = 12 impartit la 3 =4 
B= ( 1 + 6 + 7) impartit la 3=14 impartit la 3 =4,(6)
