Answer:

27 is 150% of 18

Explanation:

Let's call the percentage we are looking for "p%".

"Percent" or "%" means "out of 100" or "per 100", Therefore p% can be written as #p/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Putting this altogether we can write this equation and solve for #n# while keeping the equation balanced:

#p/100 xx 18 = 27#

#100/18 xx p/100 xx 18 = 100/18 xx 27#

#cancel(color(blue)(100))/cancel(color(red)(18)) xx p/cancel(color(blue)(100)) xx cancel(color(red)(18))= 2700/18#

#p = 2700/18#

#p = 150#
