Answer:

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

#x/100 = 9/25#

Explanation:

"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#
