Let x be the number of pages of advertisements.

Write a proportion from the table:

[tex]\dfrac{2}{3}[/tex] of a page of advertisment - 5 pages in a magazine

x pages of advertisment - 98 pages in a magazine,

then

[tex]\dfrac{\dfrac{2}{3}}{x}=\dfrac{5}{98}.[/tex]

Find x:

[tex]x=\dfrac{\dfrac{2}{3}\cdot 98}{5}=\dfrac{196}{15}=13\dfrac{1}{13}.[/tex]

Answer: 13 whole pages and [tex]\dfrac{1}{13}[/tex] of 14th page are advertisments, so 14 pages contain advertisments.
