Models N and O are shown.

Which statement is true?

A.

The shaded parts of Model N and O represent the fraction , because the shaded
areas are the same size.

B.

The shaded part of Model N can be written as fraction , because the area of each
part are equal in size.

C.

The shaded parts of Model N and O represent the fraction , because they show 1
part shaded and 1 part not shaded.

D.

The shaded part of Model N does not represent , because the parts are not all
equal in size.
