Question

Calculati media aritmetica a nr 7 supra 10 ;0,1 si 4 supra 25.Spuneti va rog clar si explicare ca nu inteleg exercitiul

Answer 1

0,1=1/10

$\frac{ \frac{7}{10} + \frac{1}{10} + \frac{4}{25} }{3} = \frac{ \frac{35+5+8}{50} }{3} = \frac{48}{50} * \frac{1}{3} = \frac{16}{50} = \frac{8}{25}$
