1,5 . n = 13,65
We know:
[tex]1,5=\frac{15}{10}[/tex]
and
[tex]13,65=\frac{1365}{100}[/tex]
So,
[tex]\frac{15}{10}.n=\frac{1365}{100}[/tex]
Pass [tex]\frac{15}{10}[/tex] as division.
[tex]n = \frac{\frac{1365}{100}}{\frac{15}{10}}[/tex]
Btw, we also know:
[tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}[/tex]
So,
[tex]n = \frac{\frac{1365}{100}}{\frac{15}{10}}[/tex]
[tex]n = \frac{1365.10}{100.15}[/tex]
[tex]n = \frac{13650}{1500}[/tex]
[tex]n = \frac{91}{10}[/tex]
[tex]n = 9,1[/tex]
