The problem can be solved by <span>proportion as following
</span>
<span>For every 15 columns of news stories in a newspaper, 4 columns of ads are required
</span>
If a newspaper contains 300 columns of news stories, x columns of ads are required
∴ 15 : 4 = 300 : x
∴
By using cross multiplication
∴ 15 x = 4 * 300
∴ 15 x = 1,200
∴ x = 1,200/15 = 80
So, the number of <span>columns of ads must it have = 80 </span>
