Models to Show Fractions Greater Than One

Ethan and Brayden each made a pie. Ethan cut his pie into eighths. Brayden cut his into sixths. The models show their pies. Ethan says they can use the models to show that 1/8 is greater than 1/6. Brayden says he is wrong. Who is right?

• Brayden is right because the models are not the same size.

• Ethan is right. 1/8 is greater than 1/6.

• They are both right.

• They are both wrong.

This model can be shaded to represent the fraction 15/9. Which number sentence represents two different ways that 15/9 can be represented with shaded fractions on the model?

• 7/9 + 4/9 + 4/9  =  3/9 + 4/9 + 7/9

• 2/9 + 5/9 + 7/9  =  5/9 + 5/9 + 5/9

• 3/9 + 2/9 + 10/9  =  2/9 + 5/9 + 8/9

• 2/9 + 6/9 + 7/9  =  9/9 + 2/9 + 3/9
