1,5 . n = 13,65

We know:

$1,5=\frac{15}{10}$

and

$13,65=\frac{1365}{100}$

So,

$\frac{15}{10}.n=\frac{1365}{100}$

Pass $\frac{15}{10}$ as division.

$n = \frac{\frac{1365}{100}}{\frac{15}{10}}$

Btw, we also know:

$\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}$

So,

$n = \frac{\frac{1365}{100}}{\frac{15}{10}}$

$n = \frac{1365.10}{100.15}$

$n = \frac{13650}{1500}$

$n = \frac{91}{10}$

$n = 9,1$
