Question

Calculati media aritimetica a numerelor:b)5,8(3)si2,1(6);

Answer 1

5,8(3) si 2,1(6)
5,8(3)= 583-58/90=525/90=175/30= =35/6 (l.am simplificat pana l.am adus la o forma mai simpla)
2,1(6)= 216-21/90=195/90=13/6 (l.am simplificat pana l.am adus la o forma mai simpla)
Media aritmetica o notam cu M:
M=(35/6+13/6):2
M=48/6 :2
M=8:2
M=4
Media aritmetica este 4
