STAAR Decomposing Fractions

The blank model shown can be shaded to represent 7/10. Which expression does NOT show a way to represent 7/10 as a sum of fractions?

• 2/10 + 2/10 + 2/10 + 1/10

• 4/10 + 3/10 - 3/10

• 6/10 + 1/10

• 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10

This model can be shaded to represent the fraction 7/4. Which number sentence represents two different ways that 7/4 can be represented with shaded fractions on the model?

• 2/4 + 2/4 + 3/4 = 5/4 + 2/4

• 3/4 + 4/4 + 1/4 = 4/4 + 1/4

• 1/4 + 1/4 + 1/4 + 3/4 = 4/4

• 2/4 + 3/4 + 2/4 = 7/4 + 1/4

The two models are shaded to represent the same fraction, 5/7: Which equation shows that the two models represent the same fraction?

• 2/7 + 3/7 + 4/7 = 4/7 + 1/7

• 2/7 + 3/7 + 5/7 = 5/7 + 1/7

• 1/2 + 1/3 + 1/4 = 1/4 + 1/1

• 1/2 + 1/3 + 1/5 = 1/5 + 1/1
