Question

Daca jumatatea unui numar necunoscut este cu 0.(3) mai mic decat 29 supra 6, aflati numarul respectiv.

Answer 1

0,(3) = 3/9 = 1/3

a/2 = 29/6 - 1/3
a/2 = (29-2) /6
a/2 = 27/6
6a = 27 ×2
6a=54
a=9

Answer 2

 [tex]\frac{n}{2}+\frac{1}{3}=\frac{29}{6}\;\;|_{\cdot6}\\ 3n+2=29\;\;\rightarrow\;\;3n=27\;\rightarrow\;n=27/3=9\;;[/tex]
