Calculati media aritmetica a numerelor 2,(3) + 3pe5 + 0,1(3)

Răspuns :

[tex]2,(3)=2\frac{3}{9}=2\frac{1}{3}=\frac{7}{3}\\ 0,1(3)=\frac{13-1}{90}=\frac{12}{90}=\frac{2}{15}\\ m_a=\frac{\frac{7}{3}+\frac{3}{5}+\frac{2}{15}}{3}\\ m_a=\frac{\frac{35+15+2}{15}}{3}\\ m_a=\frac{\frac{52}{15}}{3}\\ m_a=\frac{52}{45}[/tex]
