Let
y-------> the number of years in x months
we know that
[tex]1\ year=12\ months[/tex]
by proportion
Find the the number of years in x months
[tex]\frac{1}{12} \frac{year}{months}=\frac{y}{x} \frac{years}{months} \\ \\12y=x \\ \\y= \frac{x}{12}\ years[/tex]
therefore
the answer is the option
[tex]\frac{x}{12}[/tex]
