Multiple Choice

Compare the shaded fractions in the diagrams of images 1 and 2. How does the number of shaded parts relate to the total number of parts in each case?

• The shaded fraction is always 1/3 of the total.

• The shaded fraction is always 1/4 of the total.

• The shaded fraction changes depending on the total number of parts.

• The shaded fraction is always 1/2 of the total.
