Question

media aritmetica a lui 2,4(6) si 3,4(66) si 5,(55)

Answer 1

$\frac{246-24}{90}= \frac{222}{90}= \frac{37}{15}  \frac{3466-34}{990}= \frac{3432}{990}= \frac{572}{165}  [tex] \frac{55-5}{9}= \frac{50}{9}$
 $\frac{1221+1716+2750}{495}= \frac{5687}{495}= \frac{517}{45}$
 $\frac{517}{45}: \frac{2}{1}= \frac{517}{45}* \frac{1}{2}= \frac{517}{90}=5.7(4)$
