9 stores is 3% of 300 stores.

Explanation:

We can rewrite this as: 9 is 3% of what?

"Percent" or "%" means "out of 100" or "per 100", Therefore 3% can be written as #3/100#.

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

Finally, lets call the number of stores we are looking for "s".

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

#9 = 3/100 xx s#

#color(red)(100)/color(blue)(3) xx 9 = color(red)(100)/color(blue)(3) xx 3/100 xx s#

#900/color(blue)(3) = cancel(color(red)(100))/cancel(color(blue)(3)) xx color(blue)(cancel(color(black)(3)))/color(red)(cancel(color(black)(100))) xx s#

#300 = s#
