$n = \frac{12}{5}$ $color(green)(n = 12/5$

Cross multiply ( $\frac{a}{b} = \frac{c}{d}$ $a/b=c/d$ = $a d = b c$ $ad = bc$ )

$\frac{10}{12} = \frac{2}{n}$ $10/12 = 2/n$

$10 n = 24$ $10n = 24$

Now isolate the variable and identify $n$ $n$

$(cancel(10)n)/(cancel(10)) = 24/10$

$n = 24/10$

Simplify the fraction

$color(green)(n = 12/5$
