$color(green)(80/(57n))$

First, let's simplify each fraction.

$96/(38n) = 48/(19n) color(blue)and 25/35 = 5/9$

Now rewrite.

$48/(19n) * 5/9$

Remember that $(a/b * c/d) = ((atimesc)/(btimesd))$

$(48times5)/(19ntimes9)$

Simplify.

$240/(171n)$

Simplify again.

$(80cancel(240))/(57ncancel(171n))$

And there's your answer!

$color(green)(80/(57n))$
