Media aritmetica a doua numere se calculeaza ca suma lor impartita la cate sunt.
P.S.Voi scrie in LaTex,te rog sa dai refresh la pagina pentru a-ti aparea rezolvarea.
[tex]M_a= \frac{ \frac{3}{4}+ \frac{5}{8} }{2} =\ \textgreater \ M_a= \frac{ \frac{6}{8} + \frac{5}{8} }{2} =\ \textgreater \ M_a= \frac{ \frac{11}{8} }{2} =\ \textgreater \ M_a= \frac{11}{8} * \frac{1}{2} \\
=\ \textgreater \ M_a= \frac{11}{16} =\ \textgreater \ M_a=0,68[/tex]
