Step-by-step explanation:

Greetings !

Given expression

$\frac{10}{n} = \frac{15}{6}$

cross multiply

apply fraction cross multiply

$if \: \: \frac{a}{b} = \frac{c}{d} \: \: then \: \: a.d = b.c$

10.6=n.15

simplify:

10.6=60

Thus, 60=n.15

switch sides

$n.15 = 60$

divide both sides by 15

$\frac{n.15}{15} = \frac{60}{15}$

simplify

$n = 4$

Hope it helps!
