Decimals Using Models

Which problem is represented in the model?

• 0.32 - 0.17

• 0.49 - 0.32

• 0.32 + 0.17

• 0.49 - 0.17

Which equation matches the model?

• 0.73 - 0.23 = 0.50

• 0.50 + 0.23 = 0.73

• 0.73 + 0.23 = 0.50

• 0.73 - 0.50 = 0.23

What equation matches this model?

• 0.7 - 0.44 = 1.14 

• 1.14 - 0.44 = 0.7

• 1.14 + 0.7 = 0.44

• 0.7 + 0.44 = 1.14
