Newspaper advertisements can be  $\frac{1}{4}$  of a page,  $\frac{1}{2}$  of a page, or a full page. The shaded parts of the model show the fractions of a page used for two advertisements.

Which of the following equations represents the total fraction of the page used for these two advertisements?

•  $\frac{1}{3}+\frac{1}{3}=\frac{2}{3}$  

•  $\frac{1}{4}+\frac{1}{2}=\frac{3}{4}$  

•  $\frac{1}{4}+\frac{3}{4}=\frac{2}{4}$  

•  $\frac{1}{2}+\frac{1}{2}=\frac{4}{4}$
