Aflati n€ N astfel incat fractia 5 supra 6 sa fie echivalenta cu fractia 105 supra 10 a + 6
PLIZZZ!!

Answer 1

$\frac{5}{6} = \frac{105}{10a+6} \ \textless \ =\ \textgreater \ 6*105=5(10a+6)\ \textless \ =\ \textgreater \ 630=50a+30$
630-30=50a
600=50a
a=600:50
a=12

Answer 2

$\frac{5}{6}=\frac{105}{10a+6}$
5(10a+6)=105*6
50a+30=630
50a=600
a=12
