"Percent" or "%" means "out of 100" or "per 100".

$x/100 = 9/25$

"Percent" or "%" means "out of 100" or "per 100".

So we can solve:

$x/100 = 9/25$

$color(red)(100) xx x/100 = color(red)(100) xx 9/25$

$cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = cancel(color(red)(100))4 xx 9/color(red)(cancel(color(black)(25)))$

$x = 36$

$36%$ of the students are home sick.

Another way to solve is:

$x/100 = 9/25$

$x/100 = color(red)(4)/color(red)(4) xx 9/25$

$x/100 = 36/100$

$x = 36$
