See a solution process below:

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

Therefore x% can be written as #x/100#.

We can write and solve for #x#:

#x/100 = 18/60#

#color(red)(100) xx x/100 = color(red)(100) xx 18/60#

#cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = 1800/60#

#x = 30#

Therefore:

#30/100 = 30%# and 18 is 30% of 60
