Answer:

180 is 1,500% of 12.

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 #9/100#.

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

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

#180 = p/100 xx 12#

#color(red)(100)/color(blue)(12) xx 180 = color(red)(100)/color(blue)(12) xx p/100 xx 12#

#18000/color(blue)(12) = cancel(color(red)(100))/cancel(color(blue)(12)) xx p/color(red)(cancel(color(black)(100))) xx color(blue)(cancel(color(black)(12)))#

#18000/12 = p#

#1500 = p#

#p = 1500#
