How can understanding repeated addition help you work with fractions of a set in real-life situations?

Multiple Choice

Which equation correctly represents the fraction of 12 that is shaded in the first image?

• 12 x 1/3 = 4

• 12 x 1/4 = 4

• 12 x 1/2 = 4

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.
