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
